The software reuse has as one of its most obvious objectives to reduce the time of software development projects through the use of artifacts (parts of the system) already ready. Reuse is also related to software quality because the artifacts are being reused more widely tested for use in different projects. In this work, artifacts are all products resulting carrying out the activities of the software lifecycle and that can somehow be stored. As a contribution to reuse by recovery software artifacts repository, a search engine using genetic algorithms was developed and is presented in this article.
