Building research on smart-groups

[SemperFi]

Hello,

Using latest civicrm stable version. Is it possible to build a search on smartgroups ?
My need : finding contacts who belongs to smartgroup-1 and do not belong to smartgroup-2 ?
How should I build this request ?

FYI, I already tried : "Contacts-Groups-=-SmartGroup1-Name" and "Contacts-Groups-#-SmartGroup2-Name"

Thanks for your help

Have you tried the Include/Exclude custom search?

Awesome !! Did not know such a search exists.
Thanks very much Coleman.
