Description

Seems to be an issue parsing the query string, as the parser is trying to lookup a blank field?

In the code:

    throw new SolrException( SolrException.ErrorCode.BAD_REQUEST,"undefined field " + fieldName );

So it does print out the field name, but in my case it's blank. I got this error maybe 20 times, over 260,000 requests over the weekend.

Initially, I would submit this patch, to clarify:
