Btw "timing" for distributed requests are broken at this moment, it doesn't combine values from requests to shards. I'm working on a patch.

Traditionally, highlighting for large documents was a top culprit. Are you returning a lot of data or field values? Sometimes reducing the amount of data processed can help. Any multivalued fields with lots of values? -- Jack Krupansky -----Original Message----- From: Joel Cohen Sent: Tuesday, February 4, 2014 1:43 PM To: solr-user@lucene.apache.org Subject: Re: Lowering query time 1. We are faceting. I'm not a developer so I'm not quite sure how we're doing it. How can I measure? 2. I'm not sure how we'd force this kind of document partitioning. I can see how my shards are partitioned by looking at the clusterstate.json from Zookeeper, but I don't have a clue on how to get documents into specific shards. Would I be better off with fewer shards given the small size of my indexes?
