Subject Re: Custom filter for document permissions
Date Fri, 01 Mar 2013 01:10:05 GMT

: Actually, after thinking for a bit, it makes sense to apply the post
: filter everywhere, otherwise I wouldn't be able to know the number of
: results overall (something I unfortunately really need).

Not to mention things like facet counts, which need access to the full set 
of matching documents.

Situations like this are why using a high "cost" value are really 
important on "expensive" filters -- you want to ensure that all of the 
"cheap" filtering that can be done on your request, is done before your 
PostFilter ever gets executed, to minimize the amount of external logic 
you have to apply.

In a synthetic test like this, matching all documents w/o any other 
filtering, that "cost" is irrelevant, but it's important to remember when 
you start creating your real world requests.
