     FIELD OF THE INVENTION 
     The present invention generally relates to portable apparatuses and more particularly to providing statuses of portable apparatus. 
     BACKGROUND OF THE INVENTION 
     Mobile terminals, or mobile (cellular) telephones, for mobile telecommunications systems like GSM, UMTS, D-AMPS and CDMA2000 have been used for many years now. In the older days, mobile terminals were used almost exclusively for voice communication with other mobile terminals or stationary telephones. Gradually, the use of modern terminals has been broadened to include not just voice communication, but also various other services and applications such as www/wap browsing, video telephony, electronic messaging (e.g. SMS, MMS, email, instant messaging), digital image or video recording, FM radio, music playback, electronic games, calendar/organizer/time planner, word processing, etc. 
     With the ability to handle different content types, such as images, pictures, music, etc., the user needs to be able to find content items of these content types. 
     A known way to solve this is to provide a file browser where the user can navigate to a desired content item. However, finding the desired content item can take a significant amount of time and effort. 
     Consequently, there is a need to provide an improved way to find content items in a mobile terminal. 
     SUMMARY 
     In view of the above, an objective of the invention is to solve or at least reduce the problems discussed above. 
     Generally, the above objectives are achieved by the attached independent patent claims.

     The software also includes various modules, protocol stacks, drivers, etc., which are commonly designated as  337  and which provide communication services (such as transport, network and connectivity) for an RF interface  333 , and optionally a Bluetooth interface  334  and/or an IrDA interface  335  for local connectivity. Optionally, an internal global positioning system (GPS) receiver  345  is provided. The RF interface  333  comprises an internal or external antenna as well as appropriate radio circuitry for establishing and maintaining a wireless link to a base station (e.g. the link  102  and base station  104  in  FIG. 1 ). As is well known to a person skilled in the art, the radio circuitry comprises a series of analogue and digital electronic components, together forming a radio receiver and transmitter. These components include, i.a., band pass filters, amplifiers, mixers, local oscillators, low pass filters, AD/DA converters, etc. 
     The mobile terminal also has a SIM card  330  and an associated reader. As is commonly known, the SIM card  330  comprises a processor as well as local work and data memory. 
       FIG. 4  is a flow chart illustrating a process for searching performed in the mobile terminal of  FIG. 2 . 
     Any suitable content type can be searched, such as, but not limited to, images, songs, contacts, messages, chat histories, documents, visited web sites, bookmarks, etc. Optionally, the user can configure which content types to search and which content types to omit during search. The searched content items can be located in the mobile terminal or associated with the user and stored on equipment available to the mobile terminal through a network. For example, the search operation may search pictures/captions, documents, e-mails, etc associated with the user of the mobile terminal but stored on a server  115  available via the wide area network  112 . The user typically first needs to configure username and passwords for each network resource to connect to. 
     In a first receive search text step  450 , a search text is received from the user of the mobile terminal. 
     The actual search is performed in the perform search step  452 . Optionally, the search is performed by means of a previously populated index, making response times low. A match list is produced with all the matches to the search text. If there are no matches, it can be considered as an empty match list. 
     In the conditional match list&gt;=threshold step  454 , it is tested whether the match list has more items than a threshold number of items. This threshold can optionally be user configurable. In one embodiment, the threshold is zero items. If the match list has more items than the threshold, the process continues to a present match list step  455 , otherwise, the process continues to a present match list &amp; database search options step  456 . 
     In the present match list step  455 , the match list is presented to the user on the display of the mobile terminal. 
     In the present match list &amp; database search options step  456 , the match list along with database search options, or items, are presented on the display. If the match list is empty, only the database search items are presented. The database search items provide the user with the ability to search using a remote server, e.g. server  115  of  FIG. 1 , using the search text. The search items can for example be a person database listing people and their contact details, a business database listing business and their contact details, a web search engine, etc. In one embodiment, the user can configure the database search items, adding, editing and removing entries as desired. 
     In a conditional more search text step  457 , it is determined if the user enters more search text. If more text is entered, the process continues to the receive search text step  450 , whereby the searching is performed again. On the other hand, if no more text is entered, the process continues to a use result step  458 . 
     In the use result step  458 , the user can invoke or use a desired item presented on the display. For example, the user can view a found picture, play a found song, read a found document, call a found contact, navigate to a found contact, etc. 
       FIGS. 5   a - f  are schematic display views illustrating one embodiment of the method of  FIG. 4 . 
     The display views  560  are displayed on the display  223 / 323 . In a top section  561 , conventional status indicators are shown, e.g. for signal strength and battery level. As is conventional, in a bottom section  564 , labels for soft keys  224   b - c  are shown. In  FIG. 5   a , the user has started to enter text in a search box  563  and the mobile terminal has performed a search. The user enters the text with any suitable text input mechanism, including predictive text input, e.g. T9, multi-tap, on-screen keyboard, handwriting recognition, etc. The result of the search is shown in a match list  562 . As the user entered the text “S” in the search box  563 , all items in the match list  562  begin with the letter “S”. Optionally, the match list  562  can contain all items with at least one word beginning with the search text, in this case “S”. The items in the match list are grouped together by content type. In the match list  562  the following content types are shown: a bookmark  568  to a web page, two images  569 , two songs  570  and two contacts  571  from the phone book application. At any time, the user can select and activate any of the items of the match list  562 , e.g. by using the navigational device  226 , or the user can amend the search text. 
     In  FIG. 5   b , the user has entered another letter, whereby the search text in the search box  563  reads “Su” and the match list  562  has been updated accordingly. 
     In  FIG. 5   c , the user has entered yet another letter, whereby the search text in the search box  563  reads “Sus” and the match list  562  is updated accordingly. Now the number of matches in the match list is only one. In this embodiment, if the number of matches in the match list is less than two, additional options, or search items,  572  to search online directories are presented. These items  572  allow the user to widen search scope when local hits are too few. This provides an easy and intuitive way to search, for example, person directories, business directories, the world wide web, etc. In other words, both local and online searches are initiated in the same way. 
     In  FIG. 5   d , the user has entered another two letters, whereby the search text in the search box  563  reads “Sushi”. The match list  562  now only contains online search items  572  and no local matches. Here the first search item, a business directory search, is selected. 
     In  FIG. 5   e , the user has activated the business directory search. The search box  563  contains the same search text as previously, i.e. “Sushi”. Moreover, location information  565  can be provided to the search engine for the business directory. Here, the internal or external global positioning system (GPS) receiver is used to provide the location information  565 . Optionally, the user can enter location information  565  as text, specifying any combination of address, post code, city, country. 
     In  FIG. 5   f , the search by the business directory has been performed and the result is presented. The first match  566  of the business search is selected and the user has pressed the left soft key  224   b  to show an options menu  567 . The options menu  567  allows the user to perform a number of actions with the selected match. For example, the phone number can be dialed, the location of the business in question can be shown on a map, or directions can be given from the current position of the mobile terminal to the location of the business in the first match (e.g. using the internal or external GPS receiver for location information). 
     Although the invention has above been described using an embodiment in a mobile terminal, the invention is applicable to any type portable apparatus, including portable mp3-players, cameras, pocket computers, portable gaming devices, etc. 
     The invention has mainly been described above with reference to a few embodiments. However, as is readily appreciated by a person skilled in the art, other embodiments than the ones disclosed above are equally possible within the scope of the invention, as defined by the appended patent claims.
