Hoss Man updated SOLR-2339:
---------------------------

    Attachment: SOLR-2339.patch

Updated patch that fixes the remaining sort related test failures.

TestDistributedSearch and BasicDistributedZkTest were fundementally flawed in 
that they expected to get deterministic sort orderings on fields that they were 
deliberately putting multiple values into (ie: not just sorting on a 
multivalued field; sorting on a multivalued field that was actually used to 
store multiple values for each doc)

I'm amazed they ever passed. 

> No error reported when sorting on a field Solr knows you shouldn't sort on.

> In the past, Solr has relied on the underlying FieldCache to throw an error 
> in situations where sorting on a field was not possible.  however LUCENE-2142 
> has changed this, so that FieldCache never throws an error.
> In order to maintain the functionality of past Solr releases (ie: error when 
> users attempt to sort on a field that we known will produce meaningless 
> results) we should add some sort of check at the Solr level.
