• A full-text user-defined type is generic to text handling. It addresses the need to search and retrieve information based on aspects of full-text data using patterns such as words, phrases, proximity expansion, fuzzy expansion and thesaurus based expansions. It also addresses the need to construct such search patterns for text identification facilities and text ranking facilities.
