And set semantics are what, exactly? Membership is a primary one. "Searching in a set" in the OP's language is a demonstration of the 'in' operator, a membership/containment check. (Other equally important set semantics include intersection and union, but membership inclusion checks are definitely up there among primary purposes of sets.)
