Just wanted to clarify that commit size of 10 was only an example and in

Hi,
I am using solr 4.3 version. I am planning to use the docValues feature
introduced in solr 4.2. Although I see a significant improvement in facet
and group query , there is a degrade in group.facet and group.ngroups query.
Has anybody faced a similar issue? Any work arounds?

Hi Erick,
First Of all sorry for the late reply.
The scenario is as follows
1. Create a solr set up on two machines say (ip1 and ip2) with shard=1 and
external zoo-keeper
2. Now if i create a core x on machine with ip1 only and use the query
http://ip1:port1/solr/x/select?q=*:*distrib=false
Hi Erik,
Thanks for the reply
But does distrib=true work for replicas as well. As i mentioned earliear I
have a set up of 1 leader and 1 replica. If a core is up on either of the
instances querying to both the instances gives me results even with
