Doug Steigerwald updated SOLR-236: ---------------------------------- Attachment: SOLR-236-branch_3x.patch Attaching a patch for the 3x branch (SOLR-236-branch_3x.patch). This based off of SOLR-236-1_4_1-paging-totals-working.patch and SOLR-236-1_4_1-NPEfix.patch. Tests work and some basic spot checking I've done looks good. > 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: Shalin Shekhar Mangar > Fix For: Next > > Attachments: DocSetScoreCollector.java, > NonAdjacentDocumentCollapser.java, NonAdjacentDocumentCollapserTest.java, > SOLR-236-1_4_1-NPEfix.patch, SOLR-236-1_4_1-paging-totals-working.patch, > SOLR-236-1_4_1.patch, SOLR-236-FieldCollapsing.patch, > SOLR-236-FieldCollapsing.patch, SOLR-236-FieldCollapsing.patch, > SOLR-236-branch_3x.patch, SOLR-236-distinctFacet.patch, SOLR-236-trunk.patch, > SOLR-236-trunk.patch, SOLR-236-trunk.patch, SOLR-236-trunk.patch, > SOLR-236-trunk.patch, SOLR-236.patch, SOLR-236.patch, SOLR-236.patch, > SOLR-236.patch, SOLR-236.patch, SOLR-236.patch, SOLR-236.patch, > SOLR-236.patch, SOLR-236_collapsing.patch, SOLR-236_collapsing.patch, > collapsing-patch-to-1.3.0-dieter.patch, collapsing-patch-to-1.3.0-ivan.patch, > collapsing-patch-to-1.3.0-ivan_2.patch, > collapsing-patch-to-1.3.0-ivan_3.patch, field-collapse-3.patch, > field-collapse-4-with-solrj.patch, field-collapse-5.patch, > field-collapse-5.patch, field-collapse-5.patch, field-collapse-5.patch, > field-collapse-5.patch, field-collapse-5.patch, field-collapse-5.patch, > field-collapse-5.patch, field-collapse-5.patch, field-collapse-5.patch, > field-collapse-5.patch, field-collapse-5.patch, field-collapse-5.patch, > field-collapse-5.patch, field-collapse-5.patch, > field-collapse-solr-236-2.patch, field-collapse-solr-236.patch, > 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, > quasidistributed.additional.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.
