I agree also.
Ideally, we should define for Koha a query language syntax in BNF:
and then, create a query parser, which would validate queries, and
transform them into Zebra native syntax (3 indeed, PQF, CCL, CQL), or
transform them into coming SolR query syntax.
A standard Perl module like Regexp::Grammars could help to do the job.
