A computer-implemented system and method for augmenting search queries using glossaries is provided. At least one search query of one or more search terms is received. A set of tagged documents each associated with a tag and a glossary for the tag is accessed. The glossary includes one or more terms selected from that tagged document, definitions for the terms, and aliases for the terms. The search query is compared to the glossaries in the set. One or more terms in at least one of the glossaries that are related to the search terms of the search query are selected for inclusion in the search query.
