And just exactly how are you going to account for NOT? Remember, the syntax for NOT is something like: 
SELECT * FROM movie WHERE title LIKE 'A%' AND title NOT LIKE 'Ab%'

And the fact that i chose to use LIKE instead of = says something as well ... your interface is going to get hairy with the approach you have chosen.

Instead of parsing some user-given string, you should restrict their interface to lists and check boxes/radio buttons. Then you can create your SQL statement with something like SQL::Abstract.

L-LL-L--L-LL-L--L-LL-L--
-R--R-RR-R--R-RR-R--R-RR
B--B--B--B--B--B--B--B--
H---H---H---H---H---H---
