A search system prioritizes search-response items according to search-histories defined by two-dimensional search contexts: query context and user community. The query context is basically a query string derived from the user's search request. The community can be selected by the user or assigned by the search engine. A user can indicate interest in a search-response item by clicking on an excerpt for further exploration. The search engine associates each interest indication with the query context and the community. Thus, when an item has been returned in response to a search, a hit count for that item in the context of the present query and present community is available for prioritizing. The two dimensionally-restricted search history provides for better-targeted prioritization of search documents.
