Working on new module: Requests for Suggestions to API

Long time no blogging on use.perl journals ...

Now I'm working on a module called "WWW::GooglishQuery" that parses Googlish query parameters like XML url:foobar.com title:-"XSLT" and packs it into appropriate data structure. What's the best API for it? Maybe something like this:

use WWW::GooglishQuery;
use CGI;

my $query = CGI->new();
my $text = $query->param('q');

my $q = WWW::GooglishQuery->new();
$q->parse_query($text);

# ...

Then, how do I extract query parameters? Currently I think of returning query as hashref, that is fully compatible with SQL::Abstract module. Then we can search database with Class::DBI::AbstractSearch by passing that hashref.

Any ideas?
