I have a question about how Ferret handles intersection queries. Say I
do an intersection search on two fields, so I do ‘ruby author:(jared)’
Does Ferret do some kind of fancy index intersection to efficiently
retrieve only items that meet both queries? Or does it just find all
the ruby’s, then prune away everything that doesn’t match
author:(jared)? Does it run both searches independently, then take the
Help understanding this would be much appreciated.
