Jack Krupansky commented on LUCENE-3343:
----------------------------------------
To avoid confusion, it should be explicitly noted that this change applies only
to the Lucene "flexible" query parser, and NOT to the "classic" Lucene query
parser and hence not to any of the Solr plugin query parsers that are derived
from the classic Lucene query parser. Maybe the title should say "Flexible
QueryParser".
> Comparison operators >,>=,<,<= and = support as RangeQuery syntax in
