Subject [jira] [Updated] (SOLR-2564) Integrating grouping module into Solr 4.0
Date Wed, 08 Jun 2011 11:03:58 GMT

     [ https://issues.apache.org/jira/browse/SOLR-2564?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Martijn van Groningen updated SOLR-2564:
----------------------------------------

    Attachment: SOLR-2564.patch

Attached a new patch that should select the term based collectors now more often:
* In the case of grouping by function and the value source is StrFieldValueSource.
* All field types that produce a StrFieldValueSource (in getValueSource) use now the term
based collectors. So any custom field type can now also be supported. Both TextField and StrField
produce a StrFieldValueSource. I'm not if this is the right approach, but it was the most
easy way to implement.

> Since work on grouping module is going well. I think it is time to wire this up in Solr.
> Besides the current grouping features Solr provides, Solr will then also support second
pass caching and total count based on groups.
