The Vague Query System (VQS) due to Küng and Palkoska is an add-on to relational databases which is able to suggest alternative query results in case that an xact query fails. This is accomplished by taking numeric distances into account and, consequently, works only for queries with vague equality conditions. In this paper, we present a concept for extending VQS such that queries with vague ordering conditions can also be supported.
