    ABSTRACT: Query expansion is one of the most complex tasks in information retrieval. Several new queries can be expanded related to a user one. The problem arises in choosing the queries that are more useful for search process. Here it is supposed that the most useful expanded queries are those queries which have similar meanings with regard to the original query but the number of words that they (original and expanded query) share is low. So, their meanings are similar but grammatically they are different. So, following this idea, several experiments have been carried out to assess a fuzzy measure that is able to select which are the most useful expanded queries, i.e., a fuzzy filtering process for query expansion.
