Full-text searches use the CONTAINS predicate to locate rows that have specified text in a given column. Full-Text searches are only possible on columns that have active full-text indexes. If developers attempt to use the CONTAINS clause on a column that does not have a currently active full-text index, they will receive an error.When developers working with SQL Server “Denali”, MS SQL Server 2008 R2 and MS SQL Server 2005 want to create a full-text search query, they should follow the next steps:
1. Open a query from Solution Explorer or create a new one.
2. In the WHERE clause of their query, use the CONTAINS function to search a full-text column.
