Hi I've come across the PageHitCollector class from the: http://mail-archives.apache.org/mod_mbox/lucene-java-user/200707.mbox/%3c070320071521.6119.468a6964000b3e75000017e72205884484070a9c0701030...@comcast.net%3e
I'm looking at using this in the multisearcher class, and do: search(query,filter,pageHitCollector) I intend to use comparators to do the sorting and use collections.sort(). I would be grateful for any feedback on whether this is a good approach.
