Subject Re: Configuration for distributed search
Date Wed, 08 Aug 2012 21:40:21 GMT

: This command to each shard returns one document from each shard.
: curl 'http://localhost:8983/solr/select?debugQuery=true&indent=true&q=conway
: curl 'http://localhost:7574/solr/select?debugQuery=true&indent=true&q=conway
: This distributed search command returns 0 documents:

What do those two responses look like?  what do they look like if you add 
debugQuery=true ?

: The same distributed search command with debugQuery=true, returns an error.

Interesting ... based on your stack trace that looks like (if i'm 
understanding the code correctly) for some reason the score explanation 
info didn't come back for a document that was returned by one of the 
shards? so the data was null.  I'm not sure what that would happen, but 
i've opened SOLR-3722 to try and prevent the NPEs moving forward.
