     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0077]    Referring firstly to  FIG. 1 , a block diagram illustrating internal components of a terminal  100  is shown. The terminal includes a processor  102 . The processor  102  controls operation of the other hardware components of the terminal  100 . The processor  102  and other hardware components may be connected via a system bus (not shown). Each hardware component may be connected to the system bus either directly or via an interface. The terminal comprises working or volatile memory, such as Random Access Memory (RAM),  104  and a non-volatile memory  106 . The non-volatile memory  106  stores an operating system  108  and a search function  110 , which may or may not be a distinct application, as well as storing data files and associated metadata. The terminal comprises a display  112 . The display may be a touch sensitive display having a display part  113  and a tactile interface part  114 . The terminal may comprise one or more examples of user input hardware  116 , such as hardware keys. The terminal  100  also houses a battery  118  to power the terminal  100 . 
         [0078]    The processor  102  is configured to send and receive signals to and from the other components in order to control operation of the other components. For example, the processor  102  controls the display of content on display  112  and receives signals as a result of user inputs from tactile interface  114 . The display  112  may be a resistive touch screen or capacitive touch screen of any kind. The display may alternatively not be a touch screen. For instance it may be a liquid crystal display (LCD) 
         [0079]    The user input hardware  116  may refer to hardware keys and may also include a QWERTY or numeric keypad, a trackpad, a movement or proximity detector, a remote control or a microphone. The user input hardware  116  functions in addition to the touch sensitive display  112 , which also receives user inputs. 
         [0080]    The terminal  100  may be a mobile phone, PDA or tablet computer of any kind. Other standard or optional components of the terminal  100 , such as transceivers and cameras, are omitted. The processor  102  may be an integrated circuit of any kind. The processor  102  may access RAM  104  in order to process data and may control the storage of data in memory  106 . Memory  106  may be a non-volatile memory of any kind such as a Read Only Memory (ROM), a flash memory and a magnetic drive memory. The RAM  104  may be a RAM of any type, for example Static RAM (SRAM), Dynamic RAM (DRAM) or a Flash memory. 
         [0081]    The processor  102  operates under control of the operating system  108 . The operating system  108  may comprise code relating to hardware such as the display  112  and user inputs  116 , as well as the basic operation of the terminal  100 . The operating system  108  may also cause activation of other software modules stored in the memory  106 , such as the search function  110 . 
         [0082]    The search function  110  comprises software which receives search strings, accesses data files and metadata stored in the memory  106  and/or on a networked or cloud based storage medium, configures data for display and that causes the processor  102  to control what is output on the display  112 . For example, the search function  110  may receive a user entered search string, search an area of the memory  106  storing data files, configure a list of search results comprising representations of a subset of the searched data files and control the processor  102  to cause the list to be displayed on the display  112 . The term “search result” as used herein refers to a data file or set of data files represented by words and/or symbols on a display. The search function  110  may also control the processor  102  to cause a search application GUI to be displayed. The search function  110  may be activated in response to a specific user command, or it may activate automatically upon start-up of the terminal  100  and remain active. The search function  110  may additionally be configured to search a remote memory such as a networked drive or a cloud based network, to receive a list of search results from the remote memory and to cause the list to be displayed. 
         [0083]    In some embodiments, the search function  110  is also responsive to a user selection of a displayed search result to control the processor  102  to activate an associated function of the terminal  100 . The search function  110  also controls the processor  102  to display more or less associated information for each search result, in response to user inputs or other factors, as described in greater detail below. 
         [0084]      FIGS. 2 to 7   c  show various screen configurations which the search function  110  may control the display  112  to assume. Referring now to  FIG. 2 , a first screenshot  200  is shown being displayed on the display  112  of the terminal  100 . The first screenshot  200  shows a GUI of the search function  110 . The GUI comprises a search field  202  into which a search string can be entered. The search field  202  may be at the top edge of the display  112 . The GUI may optionally comprise a search soft key for initiating a search and a cancel soft key for cancelling an ongoing search. A user of the terminal  100  may have performed a specific action to activate the search function  110 , or the GUI of the search function  110  may be displayed automatically when the terminal  100  is in certain modes. 
         [0085]    The GUI may also comprise a soft keypad  204 . A soft keypad, also known as a virtual keypad, is a keypad that is displayed and comprises soft (virtual) keys instead of hardware keys. The soft keypad  204  may be displayed when the search function  110  is activated or, if the search function  110  is already active, when a user selects the search field  202  or otherwise enters a search string. The soft keypad  204  allows a user to enter an alpha-numeric search string into the search field  202 . In the first screenshot  200 , a user has entered “B”. The search function  110  has searched in the memory  106  and has controlled the processor  102  to cause a list of search results to be displayed in a search results window  206 . 
         [0086]    Each search result in the search result window  206  may comprise a title  208  identifying the search result, a first element of associated information  210  displayed under the title  208 , an icon  212  identifying the category of the search result and a function key  214 . Each search result may comprise one or more of the above parts. For example, each search result may comprise only a title  208 . It may alternatively include only a title  208  and a first element of associated information  210 . In these examples, the icon  212  and function key  214  are optional features. The term “associated element of information” as used herein refers to individual items of data, individual data files or sets of data files represented by words and/or symbols on a display. The function key  214  may relate to the primary function of each search result. Selection of the function key  214  by a user may cause the primary function associated with that search result to be executed. As will be seen, the parts that comprise a search result can vary during operation. 
         [0087]    Referring to the first screenshot  200 , an example is depicted in which the first search result is a contact having a title  208  “Blaise Bertrand”. The icon  212  displayed next to the title  208  indicates that this search result is a contact. The first element of associated information  210  is a primary phone number of the contact, in this instance a work phone number. The function key  214  is a telephone graphic, indicating that selection of the function key will cause the terminal  100  to dial the primary phone number of the contact. 
         [0088]    In some embodiments, the search function  110  is configured to begin searching and to control the processor  102  to display the results of the search as soon as any search string is entered into the search field  202 . As a user continues to enter characters into the search field  202 , the search is re-performed and the search results updated. 
         [0089]    Referring to  FIG. 3 , a second screenshot  300  is shown in which a user has entered the search string “Bla”. A number of criteria may be used to determine the order in which the search results are presented. For example, relevancy rules may be used to determine the order. Relevancy rules may be based on the usage history of the terminal  100 , for example a more regularly called contact or a more regularly played album appears higher on the list. Relevancy rules may also be based on calendar events, for example events occurring soon may appear higher on the list than events occurring later. Furthermore, if a contact is associated with an event, for example if the user of the terminal  100  has specified that the contact will be in attendance at the event, then that contact appears higher on the list. If the search result is a location marker or has a location associated with it, then the current location of the terminal  100  may be used so that closer locations appear higher on the list. The time elapsed since the content relating to a search result was last accessed may also be used to determine the relevancy of the search result. A combination of any of these criteria may be used. In the absence of any relevancy criteria, or in the case that these criteria are not used, then the search results are presented in another order, for instance alphabetical order. The search results may be presented in a continuous list. If there are too many search results to be displayed at once in the search results window  206 , then the user can cause the list to scroll. The results may wrap around such that that first result on the list is displayed again after the last result on the list. 
         [0090]    Referring to  FIG. 4 , a third screen shot  400  is shown in which the soft keypad  204  has been removed, allowing more of the search result window  206  to be viewed. The soft keypad  204  may be removed in response to a scroll command input initiated by the user of the terminal  100 . For example, the user may provide a vertical touch input movement in the search results window  206 , causing the soft keypad  204  to be dismissed. The scroll command input may alternatively be in the form of a hardware key press or a voice command. The circle superimposed on the screenshots  300 ,  400  illustrates a user touch input. Alternatively, or in addition, the soft keypad  204  may be dismissed when the user selects the “search” soft key (if present). 
         [0091]    A problem with the list shown in  FIGS. 2 to 4  is that only a limited amount of information associated with each search result is displayed. This is due to the limited size of the display  112  and the need to show a number of results simultaneously. Thus the user does not have access to all of the information relating to a particular search result until that search result is selected. 
         [0092]    The search function  110  is configured to cause further elements of associated information to be displayed for each of the search results while the terminal  100  is “idling”, i.e. when the terminal  100  receives no user inputs of a defined type for a predetermined length of time. 
         [0093]      FIG. 5  shows a fourth screenshot  500  which is displayed after the search function  110  has caused a second element of associated information  502  to be displayed for each search result. Each search result in the search result window  206  now comprises a title  208 , a first element of associated information  210  displayed under the title  208 , a second element of associated information  502  displayed under the first element of associated information  210 , an icon  212  identifying the category of the search result and a function key  214 . Thus the user of the terminal  100  is now presented with more relevant information for each search result. Each search result now occupies more space in the search results window  206 , and so fewer search results are displayed simultaneously. 
         [0094]    The predetermined time period in which no user input of a defined type is received may be any suitable time period, for example 1 or 2 seconds. The defined type of user input may include a scroll command input. This may be in the form of a touch screen finger swipe in the search results window  206 , a hardware key press, a voice command or any other suitable input method. The defined type of user input may also include further character entry into the search field  202  via the soft keypad  204 . Other input types, for example a touch input not within the search results window  206  or a hardware key press to change a volume level of the terminal  100  may not trigger a resetting of the time period. Alternatively, all input types may trigger a resetting of the time period. 
         [0095]    The nature of the second element of associated information  502  may depend on one or more of the search result category, the first element of associated information  210  which is already displayed and the available associated information for each individual search result. For example, the first search result visible in the fourth screenshot  400  is an album. This is indicated by the icon  212  which shows musical notes. The title  108  of this search result is the album title. The first element of associated information  210  is the album artist. The second element of associated information  502  is the first track of the album. As a further example, the third search result visible in the fourth screenshot  400  is a location marker, in this case marking the location of a shop. The title  108  of this search result is the location name. The first element of associated information  210  is the address of the location. The second element of associated information  502  is a phone number associated with the location. However, if a contact had been associated with this location, the name of the contact may be displayed as the second element of associated information  502 , instead of the phone number. 
         [0096]    Referring to  FIGS. 6   a  and  6   b , a fifth screenshot  600  is shown in which a third element of associated information  602  is displayed. If a user continues to idle while the search results are displayed as in the fourth screenshot  500 , then the search function  110  is configured to cause a third element of associated information  602  to be added for each search result. 
         [0097]    The third element of associated information  602  is added when the terminal  100  receives no user inputs of a defined type for a predetermined length of time after the second element of associated information  502  is added. The predetermined length of time may be the same or different from that described above in relation to the addition of the second element of associated information  502 . The defined type of user input may also be as described in detail above. 
         [0098]    As before, the nature of the third element of associated information  602  may depend primarily on the search result category, and also on the information which is already displayed and which is available but not yet displayed. For example, the second search result visible in the fifth screenshot  400  is a contact. This is indicated by the icon  212  which shows a human silhouette. The title  108  of this search result is the name of the contact. The first element of associated information  210  is a primary phone number of the contact. The second element of associated information  502  is a secondary phone number of the contact. The third element of associated information  602  is an email address of the contact. 
         [0099]    The process of adding more elements of associated information to each search result may continue until all of the pertinent information for each search result is displayed. For example, a contact may have several different phone numbers, an email address, an instant messaging (IM) address (such as a Skype™ name), a physical address and a personal website. The order in which the elements of associated information appear is defined by the category of the search result and may also be defined by relevancy rules, for example which of a contact&#39;s phone numbers a user most regularly calls. 
         [0100]    The search function  110  may continue to add the elements of associated information until all are displayed, or the number of elements of information for each search result may be capped, for example at 4 or 5. The number of elements of information may be capped at different levels depending on the search result category. For example, where the search result is a calendar event, the number of elements of associated information may be capped at 3 (e.g. a date/time, a location and an associated contact), even if more information is available. If no contact is associated with the event, the number may be capped at 2. Where the search result is a contact, which may have several phone numbers, email addresses and the like, the maximum number of elements may be 5 or higher. 
         [0101]    The maximum number of elements of associated information displayed for each category of search result, as well as the order in which they are displayed and the predetermined idling time intervals may be determined and updated automatically by the search function  110 . In addition these variables may be set and adjusted by a user of the terminal  100  via a settings menu. 
         [0102]    If at any point, the user inputs a new scroll command, then the search function  110  is configured to cause the number of displayed elements of associated information to be reduced back to one. Therefore any scroll input received while the display is in the format shown in the fourth or fifth screenshots  500 ,  600  causes the display to revert to the format shown in the third screenshot  400 . Thus the user is able to view a large number of search results while scrolling the list but is also able to view a much greater amount of information about each search result when not scrolling the list. Switching from viewing many search results to viewing more information for each search result is an intuitive process for the user. 
         [0103]      FIG. 6   b  shows the same fifth screenshot  600 , with a circle illustrating a user touch input superimposed. As well as displaying further information about a search result, each of the elements of associated information may be responsive to direct user selection for carrying out a related function (also referred to herein as a corresponding function). The related function may be the function most closely connected to the associated information. For example a touch input on the secondary phone number of the contact “Jack Black” causes that number to be dialled. Similarly a touch input on an email address or IM address causes an email or IM application to be opened with the selected email or IM address as the recipient while a touch input on a website causes a browser to be opened and to navigate to the website. If the associated information is an address or a location marker, selection of the address or location name causes a map application to be opened and the address or location indicated on the map. If the associated information is a track from an album, selection of the track causes that track to be played. 
         [0104]    Each of the other parts of the search results may also be responsive to selection. User selection of the title  208  (i.e. the search result itself) may cause the data relating to the search result to be displayed using an appropriate application. For example, selection of the contact name “Jack Black” may cause the terminal to navigate to the contact card for Jack Black, where all of that contact&#39;s information can be viewed. Selection of the title  208  of a meeting or other calendar event may cause the terminal to navigate to a calendar application and to select the day of the event. As a further example, selection of the title  208  of an album may cause the terminal to navigate to a media player and to begin playing the album. Selection of the icon  212  may have the same effect as selection of the title  208 , or it may have no effect. 
         [0105]    The function key  214  may relate to the primary function associated with each search result. For some search results, selection of the function key  214  may have the same effect as selection of the first element of associated information  210 . For some other search results, selection of the function key  214  may have the same effect as selection of the second, third or fourth element of associated information. For example, if the search result is a contact, the first element of associated information  210  may be a primary telephone number for that contact. Selection of the function key  214  causes the primary phone number of the contact to be dialled. As a further example, if the search result is a location marker, the first element of associated information  210  may be an address of the location. Selection of the function key  214  causes a map application to be opened and to navigate to the address of the location marker. As a further example, if the search result is a calendar event, the first element of associated information  210  could be a date and time of the event. The second element of associated information could be a location associated with the event or a contact associated with the event. Selection of the function key  214  may cause a map application to be opened and to navigate to the location if the second element of associated information is a location. Selection of the function key  214  may cause the contact card for that contact to be displayed if the second element of associated information is a contact. This function allows a user to quickly and directly initiate an action related to a search result from the search result list, without having to navigate away from the search result list. 
         [0106]    Referring now to  FIGS. 7   a  to  7   c , a further feature of the terminal  100  is illustrated.  FIG. 7   a  shows a sixth screenshot  700 . The sixth screenshot  700  has the same format as the third screenshot  400  in that only the first element of associated information  210  is displayed for each search result. However a user, particularly a user who is familiar with the function of the search function  110 , may not want to idle in order to view more information about each search result. The user can therefore force more elements of associated information to be displayed by providing a double touch input and moving the inputs apart. This type of user input is commonly used on touch screen devices to zoom in. A user may therefore find it intuitive to use this type of input to cause more detailed information to be displayed. 
         [0107]      FIG. 7   b  shows a seventh screenshot  702  in which the double touch inputs have been moved apart a small distance. This causes the second element of associated information  502  to be displayed for each search result.  FIG. 7   c  shows an eighth screenshot  704  in which the double touch inputs have been moved apart by a larger distance. This causes the third element of associated information  602  to be displayed for each search result. 
         [0108]    This process can also be performed in reverse. If a user provides a “pinch” input (a double touch input where the inputs move towards each other), then fewer elements of associated information are displayed. If the user forces more elements of associated information to be displayed using the zoom touch gesture, the removal of the additional information when scrolling may be disabled. Thus, a user may use the zoom touch input to force more information to be displayed for each search result, and may then scroll through the search results while maintaining the additional elements of associated information. 
         [0109]    Referring now to  FIG. 8 , a flow chart is shown illustrating exemplary operation of the search function  110 . At step  800  the search function  110  is started. This may occur automatically when the operating system  108  performs a specific action or when another software application is started. The search application may also be started in response to a user input. At step  802  a search is performed. As described previously, the search may be performed continuously on whatever search string that has been entered into the search field  202 . 
         [0110]    At step  804  the results of the search are displayed in the search results window  206 . Each result on the list is displayed with one element of associated information. This format is shown in  FIGS. 2 to 4 . At step  806  it is determined by the search function  110  (using the processor  102 ) whether the terminal  100  is idling. This involves determining whether the terminal  100  receives user inputs of a defined type within a predetermined time period. The time period is calculated from the moment at which the search results are displayed in step  804 , or alternatively from the time at which the user input terminated. The defined type of input may be a scroll input. If a scroll input is received within the predetermined time period, it is determined that the terminal  100  is not idling. The process returns to step  804  in which the search results are displayed with only one element of associated information. Monitoring for a scroll input within the time period may be effected by resetting and starting a timer at the beginning of the time period and determining whether a scroll input is received before the timer expires. If the timer expires before the scroll input is received, it is determined that the terminal  100  is idling. As mentioned above in relation to earlier Figures, other inputs may in some embodiments give rise to resetting of the timer. 
         [0111]    If no scroll input is received within a predetermined time period after the search results are displayed, it is determined at step  806  that the terminal is idling and the process proceeds to step  808 . At step  808  it is determined by the search application whether a limit on the number of displayed elements of associated information has been reached. Step  808  is an optional step and is performed for each of the search results individually. If the limit has been reached then the process proceeds to step  812  in which the specific search result concerned is maintained in an unchanged format. For example, the settings for a certain category of search result may mean that only one element of associated information is to be displayed. Therefore, even if it is determined that the terminal  100  is idling at step  806 , the element limit has been reached and no further elements of associated information are displayed for this search result. 
         [0112]    If step  808  is not performed, or if the result of the determination of step  808  is negative, the process goes to step  810  in which it is determined if all available elements of associated information are displayed. Step  810  is performed for each of the search results individually because each search result may have a different amount of associated information available. If all of the available elements of associated information for a specific search result are being displayed, then the process proceeds to step  812  and that search result is maintained in its current display format. If it is determined that some available elements of associated information are not being displayed, the process proceeds to step  814 . At step  814  a further element of associated information is added to the specific search result. Step  814  is represented by a change in format from, for example,  FIG. 4  to  FIG. 5 , or from  FIG. 5  to  FIG. 6   a . The additional element of associated information is added underneath the last element of associated information currently displayed. As each search result may have a different amount of associated information available, the determination at step  810  may be negative for some of the displayed search results and positive for others. 
         [0113]    After either step  812  or step  814 , the process returns to step  806 . Here, the timer is restarted and it is determined whether a scroll input is received before the timer expires. Detection of a non-scroll input resets the timer. Thus the determination of whether the terminal  100  is idling is performed repeatedly. If no user scroll inputs are received for a long period of time, then steps  806  to  810  and  814  are performed repeatedly until the element limit for each search result is reached or all of the available elements of associated information are displayed. After this, step  814  is not performed and steps  806  to  810  and  812  are performed repeatedly. As soon as the determination at step  806  is negative, the process returns to step  804 . 
         [0114]    The flow chart has no end because the determination at step  806  is re-performed repeatedly while the search function  110  is active. The process ceases when the search function  110  is no longer active. 
         [0115]      FIG. 9  is a flowchart illustrating exemplary operation of the search function  110  when user inputs to increase or decrease the amount of displayed associated information are received. If a user forces more or fewer elements of associated information to be displayed using the zoom/pinch touch gestures described with reference to  FIGS. 7   a  to  7   c , then the determination of step  806  is suspended. 
         [0116]    Referring to  FIG. 9 , steps  900 ,  902  and  904  are identical to steps  800 ,  802  and  804  respectively. At step  904 , each search result is displayed with one element of associated information. In step  906  a user input to display more elements of associated information is received. This is illustrated by the transition from  FIG. 7   a  to  FIG. 7   c . This action suspends the effect of the idling determination of step  806 . A user may then provide an input to reduce the number of elements of associated information displayed for each search result in step  908 . Steps  906  and  908  are reciprocal in that they have opposite effects, and performance of either one facilitates the other. A user may then scroll through the results at step  910 . The results are scrolled with the number of elements of associated information resulting from either step  906  or  908  maintained. The user may continue to change the number of elements of associated information displayed after scrolling, i.e. the process may return to either step  906  or  908  depending on the user input. This process has no end and is terminated when the search application is no longer active. 
         [0117]    It will be appreciated that the above described embodiments are purely illustrative and are not limiting on the scope of the claims. Other variations and modifications will be apparent to persons skilled in the art upon reading the present application. 
         [0118]    For instance, although in the above primary description initially one element of associated information is displayed and more elements are displayed after idling is detected, this is only an example. Alternatively, more or fewer elements of associated information may be displayed initially, with the number increasing after idling is detected. 
         [0119]    Also, although in the above the primary description is of the number of associated elements being displayed reverting to the initial number once further scrolling is detected, in other examples the number of associated elements being displayed once further scrolling is detected may be greater than or less than the original number. For instance, where the original number of associated elements is one, the number after scrolling may be reduced to zero or two. 
         [0120]    Moreover, the disclosure of the present application should be understood to include any novel features or any novel combination of features either explicitly or implicitly disclosed herein or any generalization thereof and during the prosecution of the present application or of any application derived therefrom, new claims may be formulated to cover any such features and/or combination of such features.
