Does SQL Server support full text search?

Full-Text Search in SQL Server and Azure SQL Database lets users and applications run full-text queries against character-based data in SQL Server tables.

Oracle Text is the equivalent functionality.

I've had good experiences with it. Assuming that you are maintaining the text index asynchronously, that tends to be the first source of problems, since it may be a bit between a change being made and the index getting updated, but that's normally quite reasonable during normal operation.
