Subject new facet parameter: facet.exists=true
Date Tue, 30 Mar 2010 11:46:24 GMT
Facetting in indexes with document volumes exceeding twenty million documents is a time and
particularly memory consuming search.

In such huge indexes i am not interested if there is 4 or 5 million documents of a special
type, i just want to know there are some and if i choose that facet will i get a list of results.

Such an option would just count the first occurance of a facet term and return it without
doing much of computation. 

I cound not figure out how to get that behaviour with existing facetting parameters. 

What do you think?
