 <!-- mm If two or fewer clauses exist, they all must match.

</requestHandler>

Phrase queries (pf, pf2, pf3) containing "dog" or "aspirin"  against the above list will not be generated.

"allergic reaction dog" will generate pf2: "allergic reaction", but not pf:"allergic reaction dog", pf2: "reaction dog", or pf3: "allergic reaction dog"

"aspirin dose in rats" will generate pf3: "dose ? rats" but not pf2: "aspirin dose" or pf3:"aspirin dose ?"
