[Fedora-directory-users] lookthrough vs. sizelimit

As I understand it, sizelimit determines the maximum number of results that 
are returned from the search, whereas lookthroughlimit determines the 
maximum number of things that will be searched in the first place.

Frankly, in our setup I have lookthroughlimit set to -1 (unlimited). Since 
the order of the searching is non-deterministic, I can't fathom any use for 
it. It has to be at least as large as your largest searchable tree, or else 
there will be entries that can never be returned in a search. If anyone out 
there is using this parameter, can you explain how/why?
