Martijn van Groningen updated SOLR-236: --------------------------------------- Attachment: field-collapse-3.patch Hey Jay, I have fixed this issue in the new patch. So if you apply the new patch everything should be fine. The compile error was a result of of the upgrade of the Lucene libraries is Solr. Because of LUCENE-1630 a new method was added to the Collector class. In this patch I also removed the invocations to ExtendedFieldCache methods and changed them to FieldCache methods. ExtendedFieldCache is now deprecated in the updated Lucene libraries. If you have any problems with this patch let me know. Important: Only use this patch from revision 794328 (07/15/2009) and up. Use the previous patch if you are using an older 1.4-dev revision. > 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 > 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-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, > SOLR-236-FieldCollapsing.patch, SOLR-236-FieldCollapsing.patch, > SOLR-236-FieldCollapsing.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.
