Method and apparatus for search optimization based on generation of context focused queries

摘要

Disclosed is a method and apparatus for operating a search system for searching a search space containing domains each representing a collection of related documents. The method includes establishing a domain characterization model (DCM) that includes a DCM index containing keywords and, for each keyword, an identification of a domain where the keyword is found. In response to an original search query, the method forms one or a plurality of enhanced search queries in accordance with the DCM for searching a plurality of domains. Each enhanced search query is formed for searching a particular targeted domain and contains the original search query and at least one keyword associated with the particular domain. The search results are clustered and are displayed so as to be organized by the domains that were searched. The top search results returned in response to each enhanced search query belong to one of the targeted domains.
