Hi, 
I have a problem, I created a full text search query which return a record(s), in which the paramater I have supplied match(es) in every fields(full-text indexed) of multiple tables. The problem is , when the user.id is equal to ceritification.AId it returns a records eventhough it was not satisfied with the parameter supplied.
For this example I supplied a value "xandrick"  which return an Id=184, but the problem is it returns two ids which is 184 and 154.What is the best way to return an ID(s) that satisfied of the supplied given value?
