ldap filter order

Hello, I have

10 000 objects with attributeA=john

and

100 of these objects has also attributeB=mary

both attributes are indexed.

Does it make any difference between

(&(attributeA=john)(attributeB=mary))

vs.

(&(attributeB=mary)(attributeA=john))

I bet it is better to exclude john-matched objects from the set of 100 mary-matched objects, than exclude 100 mary-matched objects from the set of 10 000 john-matched objects, is that right?

In other words - does it make sens to order complicated filters to match possible low-volume results from the left, and high-volume sets on the right? This, of course, apply to AND filters only.
