One of the key benefits of XML is its ability to represent a mix of structured and text data. Querying XML is a well-explored topic with powerful database-style query languages such as XPath/XQuery set to become W3C standards. However, these languages are not powerful enough to express full-text search queries. For this reason, we developed TeXQuery, a full-text extension to XPath/XQuery which provides a rich set of fully composable full-text search primitives, such as keyword and Boolean search, proximity distance, stemming and regular expressions and gracefully combines them with structured search with XPath/XQuery. TeXQuery is the precursor of XQuery Full-Text, the current full-text extension to XPath 2.0 and XQuery 1.0 that is being developed by the W3C. TeXQuery also supports a flexible scoring construct that allows users to express queries such as return
