Hoss Man commented on SOLR-1171:
--------------------------------
bq. lthough solr does not enforce field name restrictions adding spaces makes a
few things not work. It seems better to make the restriction explicit rather
then wait for things to go wrong.
eh ... some features may not work if your field names contain spaces, but that
doesn't mean we should make it an error to try and do it if you don't use those
features. The Elevation component requires you have a uniqueKey, but that
doesn't mean uniqueKeys are mandatory for all indexes -- it just means thta
feature is smart enough to check when it's prereqs aren't met. QueryParser
doesn't support "special charcters" in field names, but that doesn't mean we
should explicitly forbid them.
I don't even understand why LukeRequestHandler is using QueryParser ... it's
just building an unbounded RangeQuery to find out how many documents contain
this field... that can be done without parsing.
