Timeouts in distributed search using Solr + Zookeeper

["Cinquini, Luca (3880)" <Lu...@jpl.nasa.gov>]

Hi,
	we are looking at Solr+Zookeeper as the architecture for enabling federated searches among geographically distributed data centers.

I wonder if anybody can comment on what is the status of enabling timeouts with respect to distributed searches in a Solr-Zookeeper environment. Specifially, following the example C) in the Solr Cloud wiki:

http://wiki.apache.org/solr/SolrCloud

it seems like the system is resilient to any Solr server (out of 4) being unavailable, but if both Solr servers serving the same shard go down, then a distributed query results in error, instead or returning partial results. Is there any special configuration that needs to be set for the Solr and/or Zookeepers servers, or any request parameter that needs to be added, to make the distributed query just return results from the only available shard ? Or maybe this feature is not yet operational ?

thanks a lot,
Luca
