The most Web search sites provide with a function of query recommendation for users, however, the function may not be necessarily easy to use for users who are not familiar with the area to search. In this study, we aim to develop a method to recommend proper query terms for such users by providing with terms that are observed at postings in Q&A sites. As results of analyzing the postings in Q&A sites, we find a possibility to develop our method to provide with proper terms for users who are not necessarily familiar with the area to search.
