In this report, we describe the results of an experiment designed to measure the effects of automatic query expansion on retrieval effectiveness. In particular, we used a collection-specific thesaurus to expand the query by adding synonyms of the searched terms. Our preliminary results show no significant gain in average precision and recall.
