In this patch you return a partial result when a shard has failed by setting partialResults
to true in the request or if you want it to for all requests your can add <bool name="return-partial-results">true</bool>
to your search handler in your solrconfig.xml. If both are not specified, partial results
are disabled. Currently the partialResults parameter overrides the return-partial-results
property in the search handler.

I'm not sure about the need for the return-partial-results static boolean. This could just
be handled through the RequestHandler defaults, right?

> 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?
