David Smiley commented on SOLR-435:
-----------------------------------
I'm onboard with SOLR-2001. My 1st concern was the NPE, my 2nd was a non-error
default, my 3rd was *:*. I can't have everything :-)
I did consider the approach in SOLR-2001 which is to return null from
QParser.parse() but I wasn't sure if that would be disruptive to any implied
contract/expectation. I guess there's no issue with that.
I'll try and attach a back-ported patch soon.
