The technology is inserted in the most diverse environments of society, however, at times its use can be improved, as in the case of web search engines. Search tools on the web, when used by elementary school children, can lead to a complex environment that hinders learning. Such an occurrence is due to the little familiarity of children in formulating questions related to what they need to learn and the difficulty in interpreting the results. Due to this difficulty, this work proposes a search engine that improves the search string considering what governs the Base Nacional Comum Curricular. To implement this mechanism, text mining is used, to improve the environment for children's learning. As a form of evaluation, elementary school students were used together with the collaboration of teachers with the same profile. Thus, it is possible to evaluate the use of the tool and conclude the occurrence of improvement in educational search results when using a tool that applies text mining techniques in a search engine.
