Yeah I need something like: (id:1 and maxhits:1) OR (id:2 and maxits:1).. something crazy like that..
I'm not sure how I can hit solr once. If I do try and do them all in one big OR query then I'm probably not going to get a hit for each ID. I would need to request probably 1000 documents to find all 100 and even then there's no guarantee and no way of knowing how deep to go. -Kallin Nagelberg -----Original Message----- From: dar...@ontrenet.com [mailto:dar...@ontrenet.com] Sent: Thursday, May 20, 2010 12:27 PM To: solr-user@lucene.apache.org Subject: RE: seemingly impossible query I see. Well, now you're asking Solr to ignore its prime directive of returning hits that match a query. Hehe. I'm not sure if Solr has a "unique" attribute. But this sounds, to me, like you will have to filter the results yourself. But at least you hit Solr only once before doing so.
