Now, the filters are working VERY WELL.
Sorry but I did nothing special, MAYBE it’s because I recreate my DataBase with the automatic generated script , and I DIDN’T keep the folowing instructions :

IF (1 = FULLTEXTSERVICEPROPERTY(‘IsFullTextInstalled’))
begin
EXEC [BDNvpCode].[dbo].[sp_fulltext_database] @action = ‘enable’
end
GO

And after I restore it :

Name of DataBase -> Tasks -> Restore

But nothing is less sure…

Think You very much and see you later !
