very nice rewrite
Heiya John, I agree that this page should be worked on. It should be easier to grasp what it is all about. I am however not so sure about renaming this to predicate though I understand your point, at least I think I do. :) Cheers
I think a more appropriate title would be "Help:Inverse queries" and the page should be listed in the menu under "Inline queries" (rather than "Properties", as it is now).
