I guess this is effective, but not efficient whatever language
you use ;-)

That uses substring matching I guess, which is not efficient
in this case.

Here you use the quality of dictionaries, which provide quick

How to search for the codes with the most hits is another story :-)

I guess the Catalog doesn't support OR searches, which would
do what you need.
