This module provides an object that matches a data source against a query expression. Query expressions are compiled into an internal form when a new object is created or the `prepare' method is called; they are not recompiled on each match. The class provided by this module uses four packages to process the query. The query parser parses the question and calls a query expression builder (internal form of the question). The optimizer is then called to reduce the complexity of the expression. The solver applies the expression on a data source. WWW: https://metacpan.org/release/Text-Query
