A search system provides various techniques for facilitating information retrieval. The search system may identify alternate queries for an initial query submitted by a user to a search system. Upon receiving the initial query, the search system identifies questions that are related to the initial query and presents to the user the related questions as alternate queries. The search system may also identify messages within a discussion thread that include answers. The search system may also identify an expert relating to the subject of a query by searching through expert profiles containing keywords of discussion threads in which the expert participated. |
