Glossary of terms relating to thesauri and other forms of structured vocabulary for information retrieval

Search thesaurus

vocabulary intended to assist searching even though it has not been used to index the documents being searched

Search thesauri are designed to facilitate choice of terms and/or expansion of search expressions to include terms for broader, narrower or related concepts, as well as synonyms. Optionally, a normal thesaurus may be used as a search thesaurus.
