Re: result grouping?

Hi, I don't know if solr can manage grouping. But you can do it using an XSLT stylesheet: http://www.jenitennison.com/xslt/grouping/muenchian.html Hope it helps :) On 1/2/07, Ryan McKinley <[EMAIL PROTECTED]> wrote: Is it possible to group the results from a solr query? I have indexed the c

thanks. Yes, the presentation layer could group results, but that is not practical if i want to show the first 20 results out of 200,000 matches. Nutch groups the results by site. Any idea how they do it? thanks ryan On 1/3/07, Ricardo Borillo <[EMAIL PROTECTED]> wrote: Hi, I don't know if

Re: How to tell the highlighter not to escape?

for what it's worth, i wrote a recursive template in xsl that replaces the escaped characters with actual elements. here, the variable $val would be the tag, e.g. "em". this has been working okay for me so far.

Based on a chat with an early adopter of Flare, we decided to split out the Ruby-Solr DSL sooner rather than later. I've pulled out the library code into a separate directory under client/ruby/solrb ("rb" being the standard Ruby file extension). Info for this library is here:
