Abstract
Tools and techniques are described herein for detecting synonyms and merging synonyms into search indexes. The tools provide methods that include receiving input documents for indexing into a search index file. The tools may compare parts of the input documents to parts of other documents already indexed into the search index file. The methods may also evaluate, based on these comparisons, whether the input document and the existing document are sufficiently similar to justify an inference that any dissimilar terms between the input document and the existing document are candidate synonyms. Other methods may include receiving requests to perforin searches that include one or more input keywords. The method then searches for links to synonyms of the input keyword, and returns search results responsive to the input keyword and to the synonyms.
