Subject Re: Execution of Queries in Parallel: geotagged textual documents in Solrvvvv
Date Tue, 09 Apr 2013 16:34:41 GMT

I'd move to SolrCloud 4.2.1 to benefit from sharding, replication, and
the latest Lucene.  How many queries you will then be able to run in
parallel will depend on their complexity, index size, query
cachability, index size, latency requirements... But move to the
latest setup first.
