Open ontology-described repositories are becoming very common in the web and in enterprises. These repositories are well-suited to answer complex queries, but in order to fully exploit their potential, the queries should be written in a user-demand basis, and not in a traditional static approach by software developers. Hence, the users are required (i) to know the underlying ontology(ies) and/to (ii) write formal queries. Yet, the users often lack such requirements. In this paper we first describe the observations made during manual complex querying process and present a systematization of the users' support wish list for building complex queries. Based on this systematization we propose an extended set of functionalities for a user-supporting system. Finally, we demonstrate their application in a walk-through example and their implementation within a prototype.
