Thanks all! One last question... If I had a collection of 2.5 billion docs and a demand averaging 200 queries per second, what's the confidence that Solr/Lucene could handle this volume and execute search with sub-second response times?

It's down to about 7.8 million currently. I have seen no signs of a "maximum" number of docs Solr can handle. -----Original Message----- From: Chris Harris [mailto:[EMAIL PROTECTED] Sent: Wednesday, September 26, 2007 11:49 AM To: solr-user@lucene.apache.org Subject: Re: dataset parameters suitable for lucene application By "maxed out" do you mean that Solr's performance became unacceptable beyond 8.8M records, or that you only had 8.8M records to index? If the former, can you share the particular symptoms?
