Martijn van Groningen commented on SOLR-1143:
---------------------------------------------
Sure, that is a good idea. I think that also other types of exceptions should
result in a partial result (currently just a connection timeout will result in
a partial result). I think that this behaviour should be enabled with a
parameter in the request. Something like _shards.requestTimeout=1500_ (time is
in ms).
> Return partial results when a connection to a shard is refused

> 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?
