Hoss Man updated SOLR-435:
--------------------------
Attachment: SOLR-435_3x_consistent_errors.patch
patch against 3x that ensures the parsers likely to be used as defaults
(lucene, lucenePlusSort, dismax, and edismax) give consistent ParseExceptions
when the query sting is null or missing.
this seems to be along the lines of what smiley and male where suggesting for
3.6, and then we could open a new issue to re-evaluate if/where the error
handling/reporting of QParsers in general is lacking for 4.0 or if there should
be different defaults (given that SOLR-2001 already made changes relate this
this dicussion on trunk)
> QParser must validate existence/absence of "q" parameter
