------------------------------------
Attachment: SOLR-7254.patch
Here's a patch to start things off. I haven't tested this as yet or added tests for this as yet. [~hgadre], if you can knock up some tests for this, that would be great, else I will probably get to it some time. You can start at {{TestDistributedSearch}}.
