Abstract
A system and method for providing full-text search integration in XQuery is presented. A built-in search function defined in an XQuery language is implemented, and a full-text search is initiated. The search function includes one or more search terms and a relation logic. Variants for each search term in the search function are identified. Posting lists are obtained for one or more of the variants. Each posting list includes values offset from elements containing the search term associated with the variant to which the posting list corresponds. The relation logic is applied to the offset values of the posting lists. Those elements with offset values that satisfy the relation logic are selected. The elements that satisfy the relation logic are provided as results of the full-text search.
