How to perform a full text search

You can perform a full text query either by using a CONTAINS clause in the FROM clause of a SELECT statement, or by using a CONTAINS search condition (predicate) in a WHERE clause. Both return the same rows; however, use a CONTAINS clause in a FROM clause also returns scores for the matching rows.

The following examples show how the CONTAINS clause and search condition are used in a query. However, if you run these examples in Interactive SQL they will fail because you have not built a text index on MarketingInformation.Description yet.

SELECT *
   FROM MarketingInformation CONTAINS ( Description, 'cotton' );
SELECT *
   FROM MarketingInformation
   WHERE CONTAINS ( Description, 'cotton' );
