Bojan Smid updated SOLR-236: ---------------------------- Attachment: solr-236.patch I updated the patch so that it can be compiled on Solr trunk. Also, since CollapseComponent essentially copied QueryComponent's prepare method (and it seems that it is supposed to be used instead of it), I made it extend QueryComponent (with collapsing-specific process() method, and prepare() method inherited from super class). > Field collapsing > ---------------- > > Key: SOLR-236 > URL: https://issues.apache.org/jira/browse/SOLR-236 > Project: Solr > Issue Type: New Feature > Components: search > Affects Versions: 1.3 > Reporter: Emmanuel Keller > Assignee: Otis Gospodnetic > Attachments: field-collapsing-extended-592129.patch, > field_collapsing_1.1.0.patch, field_collapsing_1.3.patch, > field_collapsing_dsteigerwald.diff, field_collapsing_dsteigerwald.diff, > field_collapsing_dsteigerwald.diff, SOLR-236-FieldCollapsing.patch, > SOLR-236-FieldCollapsing.patch, SOLR-236-FieldCollapsing.patch, solr-236.patch > > > 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.
