[jira] [Updated] (SOLR-2066) Search Grouping: support distributed
search
[ https://issues.apache.org/jira/browse/SOLR-2066?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Martijn van Groningen updated SOLR-2066:
----------------------------------------
Attachment: SOLR-2066.patch
Updated the patch, so that is up to date with the trunk. The code compiles, but the test still fails.
In order to support distributed grouping properly we need a new distributed stage. This stage uses only the first phase collector and only retrieves the top groups.
All the top groups from the different shards can be merged with the utilities Lucene grouping module provides (GroupMerger). The groups that survive the merge are send to back to the shard where the came from in the next phase.
After the merge the normal query stages kick in. But on the shard side only the second phase collector is used.
