Abstract:
1. An interactive multi-prefix and multi-tier search system, comprising a non-transitory computer-accessible storage medium, that searches a database of content items across a plurality of channels, each channel representing a category of content items within the database, the system comprising: (a) a multi-prefix word index, generated by the system and embodied in a non-transitory computer-accessible storage medium, that contains: (b) a multi-prefix search module, generated by the system and embodied in a non-transitory computer-accessible storage medium, that receives keystrokes as they are entered by a user into a device, and searches the multi-prefix word index for content items within the database that contain words having a prefix matching the keystrokes; (c) a multi-tier search module, generated by the system and embodied in a non-transitory computer-accessible storage medium, that limits a first search, including a first set of keystrokes, to a first tier of content that contains names of channels in the database, and, upon receiving an indication of the user's selection of the name of a first channel, limits a second search, including a second set of keystrokes, to a second tier of content that contains items within the category represented by the name of the first channel; and (d) a search result delivery module, generated by the system and embodied in a non-transitory computer-accessible storage medium, that delivers the matching content items generated by the multi-prefix search module to the device for display to the user.
