You can put a substring in double quotes to force it to be interpreted Text search dictionaries convert tokens to normalized form and reject stop words. • Text search templates provide the functions underlying dictionaries. (A dictionary simply specifies a template and a set of dictionaries to use to normalize the tokens produced by the parser. Text search parsers and templates are built from low-level C functions; therefore it requires C pro- gramming ability to develop new
