Poliqarp: An open source corpus indexer and search engine with syntactic extensions

This paper presents recent extensions to Poliqarp, an open source tool for indexing and searching morphosyntactically annotated corpora, which turn it into a tool for indexing and searching certain kinds of treebanks, complementary to existing treebank search engines. In particular, the paper discusses the motivation for such a new tool, the extended query syntax of Poliqarp and implementation and efficiency issues.
