FREETEXT is an SQL text-search predicate that uses stemming (e.g. -ing, -ly) and a thesaurus to search for the given string.
FREETEXT is a predicate used to search columns containing character-based data types for values that match the MEANING and not the exact wording of the words in the search condition. When FREETEXT is used, the full-text query engine internally performs the following actions on the freetext_string, assigns each term a weight, and then finds the matches.
