The increased amount of information in different domains, complicating the quick access to a particular need or specific query of any person or user, so arises the need to expedite this need, where the initial query is sought within a set of a domain documents chosen by the user. To retrieve more documents is important to incorporate techniques that allow to get more documents with the desired information. In this case extend the original query with the synonyms of the words that compose it can

In this paper, we propose an algorithm for query expansion of a Boolean Information Retrieval System (BIRS), in which the queries are formed by the concepts of four domain ontologies. According to the experimental results, we observe an improvement in the accuracy of the BIRS with the query expansion.
