Shreejay commented on SOLR-2592:
--------------------------------
Hi Yonik,
What configuration (solrconfig / solr.xml /schema.xml / ZK ?) do I have to
change in order to use these changes in trunk? I have a string field on which I
want to do "group by" and hence I want all documents with same value of the
string field to be on same side.
I was using a 4x branch with Michael's patch, but ran into heap space issues
mentioned in https://issues.apache.org/jira/browse/SOLR-4144 . I was not able
to merge trunk to 4x and just saw your comment that you also had issues while
doing this.
So my next step might be to use the trunk directly with the patch supplied for
4144. How do I specify that I want to shard based on a specific string field?
Thanks.

> If the data in a cloud can be partitioned on some criteria (say range, hash,
> attribute value etc) It will be easy to narrow down the search to a smaller
> subset of shards and in effect can achieve more efficient search.
