Abstract
In this work we present a heuristic for query expansion and its evaluation with information retrieval over the Internet. We obtained the precision and recall measures for the top-50 documents from 13 different queries. For those we had good results on estimated recall and F-measure values indicating that query expansion is a reasonable technique when few documents are retrieved.
