Searching in THOMAS is performed by the InQuery information retrieval system, developed by the Center for Intelligent Information Retrieval based at the University of Massachusetts at Amherst.
InQuery employs a relevance-ranking algorithm for searching and displays the most relevant items first on the results list. Experienced searchers who wish to use Boolean searching may use native InQuery syntax to override the relevance-ranking default.
