Not published to CPAN, AFAIK.

Be aware that FlatQueryParser is "flat" because it doesn't support nested
parenthetical groups -- or any other logical groupings for that matter.
Creating a parser than handles those will involve work not covered in the
cookbook entry.

Have at it.  

As far as the name goes, that sounds like "the definitive" QueryParser...
almost like KS didn't have one.  It will likely be the first one people check
out outside of core.  Is it your ambition to write a kitchen-sink complete
parser?

That'd be lovely if it was.  I'm very interested in core KS providing building
blocks and tutorials to support the development of alternate parsers, but I'm
totally uninterested in the specifics of query language syntax.
