Context-aware search

摘要

One embodiment of the present invention sets forth a technique for supplementing user-specified text for a search with context information to generate search results that is more closely matched to the user's needs. A context search component maintains a snapshot of the user context and additional context-based queries are generated and corresponding searches are performed. The search results of the context-based queries are merged with the results of the user-specified text query and displayed for the user. When the user accesses a resource listed in the merged search results, the context-based terms mentioned in the resource are identified to the user.

1. A computer-implemented method for generating context-based queries, the method comprising:
receiving a user-specified query that includes a user-specified term; extracting a context-based term from context data associated with an application program, wherein the context data includes one of an indication of a state change associated with the application or an indication of an action triggered by a user interacting with the application; generating a context-based query that includes the context-based term by combining the user-specified query with the context-based term; receiving first search results for the user-specified query and second search results for the context-based query; and ranking resources listed in the first search results and resources listed in the second search results to generate merged context-based search results.
