One implementation provides a method included in performing a computer-implemented search of electronically stored content. The method includes receiving from one of multiple software applications an input indicating a user request that a computer-implemented search be performed to identify content that, firstly, is stored in a specified one of multiple knowledge bases, and secondly, satisfies user-specified conditions. The method further includes determining which one of multiple search engines has been preconfigured to be used for searches involving the one software application from which the search request input was received and the selected one knowledge base, and initiating the requested search to be executed by the determined search engine.
