If you are running Sharepoint with SQL (not WMSDE), you’re supposed to be able to perform full text searchies. If searching is not working for you, make sure it’s enabled. Here’s how:
1. Click Start > Administrative Tools > Sharepoint Central Administration.
2. Scroll down to the Component Configuration section
3. Click on the Configure full text search link
4. Click the box to enable full text search
5. Click OK, and then wait several seconds while it updates.
