Merge and interect precedence

Hi,

i’m actually working on a project where i need to do a DB Query which would require a merge and then an intersect with the merge result.

the query would look like : (Query1 merge Query2) intersect with Query3 …

Is there a way to indicate precedence regarding query in a Do Search for ?

(@NigelG, you did a great job on this thread : SQL Joins Vs Bubble . Any hint about my question ?)

thanks for your help !

Best regards,

Guillaume
