This may be the old hammer-maintainer sees all things as nails, but if you use DBD::CSV you can leverage Text::CSV_XS's parsing speed and SQL's sorting and selecting options and DBIx::*'s rich set of output formats. If speed is an issue, use DBI::SQL::Nano as DBD::CSV's parser instead of SQL::Statement - it's much more limited but also much faster for simple key-field queries.

Or then again, maybe you're asking about search logic rather than software, in which case the answer could depend on a the best combination of Perl and SQL processing.
