3.      In SQL Server Management Studio, select the instance in which you want to enable IFilters, and then run the following command in that instance:
sp_fulltext_service 'load_os_resources', 1
4.      If you are running SQL Server 2008, go to Step 5. If you are running SQL Server 2005, stop and restart the msftesql service. To do this, follow these steps:
a.       At a command prompt, type the following command and then press Enter:
net stop msftesql
Note To stop the msftesql service for a specific instance, run the following command:
net stop msftesql$InstanceName
b.       At a command prompt, type the following command and then press Enter:
net start msftesql
Note To start the msftesql service for a specific instance, run the following command:
net start msftesql$InstanceName

5.      Restart the SQL Server service.

I did these things and have the same result. The query I am running is in Query Analyzer:

SELECT * FROM ContainsTable([editionArticle], pdf, '"Sale"') and returns empty.

a similar query run agains a nvarchar field "SELECT * FROM ContainsTable([editionArticle], Title, '"Supertest2"')" returns the Primary key and a rank.

it worked for me

Thanks emoreau, I wish it had worked for me. There is probobly something stupid and simple that I am missing. I do appreciate the input. THANKS :-)
