The query response features described in this section provide information that allows users to refine their searches, making the results more precise. The following tools are available:
Categorization feedback—Which categories are related to the query terms
Spelling correction—What query terms the user might have intended to use
Preconfigured query refinements—Uses metadata to provide refinement suggestions
Categorization feedback, spelling suggestions, and query term feedback are all part of query refinement. Categorization feedback allows users to restrict the search space to a relevant category. Spelling suggestions allows end users to correct mistakes or try alternative terms. Query term feedback allows users to add relevant terms to their query.
