      Description

      This patch include a new feature called "Field collapsing".

      "Used in order to collapse a group of results with similar value for a given field to a single entry in the result set. Site collapsing is a special case of this, where all results for a given web site is collapsed into one or two entries in the result set, typically with an associated "more documents from this site" link. See also Duplicate detection."
      http://www.fastsearch.com/glossary.aspx?m=48&amid=299

      The implementation add 3 new query parameters (SolrParams):
      "collapse" set to true to enable collapsing.
      "collapse.field" to choose the field used to group results
      "collapse.max" to select how many continuous results are allowed before collapsing

      TODO (in progress):

      • More documentation (on source code)
      • Test cases

          Looks like I missed something... yes, SOLR-236 applies to trunk fine. I didn't notice it because I was looking at this issue.

          Since any further development/integration should happen on SOLR-236, I think we should close this issue and mark it as a duplicate.

          I'll put my substantive comments on SOLR-236...

          I provided two patch.

          The first was made off current trunk (see solr-236). And this one (solr-237) for release 1.1.

          Is that correct ? Or did I miss something ?

          Thanks for posting this Emmanuel!

          I'm having trouble applying the patch... I get an error that says something like "this patch seems outdated!"

          Did you build it with a recent svn checkout?

          thanks
