This article describes POLIQARP, a corpus indexing and query tool, which understands positional tagsets and which does not assume that word forms are annotated with unique morphosyntactic tags. POLIQARP is designed to be applicable to a variety of languages and tagsets: it works with XML-encoded texts, uses the UTF-8 character set, and allows for an external specification of the tagset. Currently, POLIQARP is used for indexing and searching a morphosyntactically annotated corpus of Polish.
