I've recently used solr's FunctionQuery to do just this with great success. Take a look at FunctionQuery and ReciprocalFloatFunction.

I don't want to do a strict sort by date. Is this supported somehow by using a dismax request handler? Or if you have other hints, I'm eager to know what they are. dismax handler has a bf (boosting function) parameter that may be used to specify a function over the date field. You could try something like setting bf to recip(rord(mydatefield),1,1000,1000)^0.5 A reciprocal function over the reverse ordinal of the date field, with a weight of .5 (adjust weight until you get the right balance) http://incubator.apache.org/solr/docs/api/org/apache/solr/request/DisMaxRequestHandler.html -Yonik
RE: client code for searching?
I've been meaning to write some companion code to do searching. I haven't needed to search from Java yet, so I haven't written it. Expect it in a few weeks given my current schedule. -D -Original Message- From: Brian Lucas [mailto:[EMAIL PROTECTED] Sent: Friday, July 14, 2006 12:10 PM To: solr-user@lucene.apache.org Subject: RE: client code for searching? http://wiki.apache.org/solr/SolJava -Original Message- From: WHIRLYCOTT [mailto:[EMAIL PROTECTED] Sent: Friday, July 14, 2006 1:03 PM To: solr-user@lucene.apache.org Subject: Re: client code for searching?

Solr has integrated highlighting
Those who aren't subscribed to solr-dev may be interested to know that the lucene highlighter has been integrated into Solr, for both the standard request handler, and the dismax handler. See the highlight, highlightFields, and maxSnippets params documented here: http://wiki.apache.org/solr/StandardRequestHandler When highlighting is enabled, a new highlighting section is added to responses. Highlighted terms are marked up like so: emterm/em Below is a sample for query terms ipod, USB In the real response, the markup tags em/em are XML escaped so each highlight snippet is a single string. lst name=highlighting lst name=IW-02 arr name=features strcar power adapter for emiPod/em, white/str /arr arr name=name stremiPod/em emiPod/em Mini emUSB/em 2.0 Cable/str /arr /lst lst name=MA147LL/A arr name=features strplayback, Upgradeable firmware, emUSB/em 2.0 compatibility, Playback speed control, Rechargeable capability/str /arr arr name=name strApple 60 GB emiPod/em with Video Playback Black/str /arr /lst /lst The Lucene version in Solr was just updated to fix a highlighting bug with overlapping tokens, so you may want to wait for the 7/16 nightly solr build if you use WordDelimiterFilter. -Yonik
Re: client code for searching?
I added my code to jira in case anybody's interested. https://issues.apache.org/jira/browse/SOLR-30 phil.
