Yuriy Akopov commented on SOLR-236: ----------------------------------- Another question: The patched version of .war starts and works as expected if I place the following simple instruction in solrconfig.xml: <searchComponent name="collapse" class="org.apache.solr.handler.component.CollapseComponent"> </searchComponent> But if I add additional factories like it is advised by the sample config, it produces an error when searching with collapsing turned on: <searchComponent name="collapse" class="org.apache.solr.handler.component.CollapseComponent"> <collapseCollectorFactory class="solr.fieldcollapse.collector.DocumentGroupCountCollapseCollectorFactory" /> <collapseCollectorFactory class="solr.fieldcollapse.collector.FieldValueCountCollapseCollectorFactory" /> <collapseCollectorFactory class="solr.fieldcollapse.collector.DocumentFieldsCollapseCollectorFactory" /> <collapseCollectorFactory name="groupAggregatedData" class="org.apache.solr.search.fieldcollapse.collector.AggregateCollapseCollectorFactory"> <function name="sum" class="org.apache.solr.search.fieldcollapse.collector.aggregate.SumFunction"/> <function name="avg" class="org.apache.solr.search.fieldcollapse.collector.aggregate.AverageFunction"/> <function name="min" class="org.apache.solr.search.fieldcollapse.collector.aggregate.MinFunction"/> <function name="max" class="org.apache.solr.search.fieldcollapse.collector.aggregate.MaxFunction"/> </collapseCollectorFactory> </searchComponent> So far it does what I expect from it without additional factories mentioned, but still it bothers me that it fails when they're listed. Maybe I placed the libraries in a wrong place? > 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.
