Abstract
Embodiments of the invention relate to automatically suggesting query-rewrite rules. One embodiment includes providing a missing search result for a query. A collection of semantically coherent rewrite rules are generated based on the missing search result. Generating the missing search result includes: selecting candidates including subsequences of the query and subsequences of particular fields of a document, invoking a search engine using the candidates for providing search results, filtering out particular candidates that fail to achieve a desired search result, and classifying remaining candidates based on a learned classifier. Query rewrite rules for document searching are suggested based on the classified remaining candidates.
