Gerald DeConto commented on SOLR-236: ------------------------------------- I have been able to apply and use the solr-236 patch successfully. Very, very cool and powerful. Are there any plans/hacks to include the non-collapsed document in the collapseCount and aggregate function values (ie so that it includes ALL documents, not just the collapsed ones)? Possibly via some parameter like collapse.includeAllDocs? I think this would be a great addition to the collapse code (and solr functionality), via what I would think is a small change, since solr doesnt have any other aggregation mechanism (as yet). Am trying to see how to change the code myself but Java is not my primary language. > 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: 1.5 > > Attachments: 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-FieldCollapsing.patch, > SOLR-236-FieldCollapsing.patch, SOLR-236-FieldCollapsing.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 > > > 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.
