    Description

      If any shard is down in a distributed search, a ConnectException it thrown.

      Here's a little patch that change this behaviour: if we can't connect to a shard (ConnectException), we get partial results from the active shards. As for TimeOut parameter (https://issues.apache.org/jira/browse/SOLR-502), we set the parameter "partialResults" at true.

      This patch also adresses a problem expressed in the mailing list about a year ago (http://www.nabble.com/partialResults,-distributed-search---SOLR-502-td19002610.html)

      We have a use case that needs this behaviour and we would like to know your thougths about such a behaviour? Should it be the default behaviour for distributed search?
