in reply to Matching values between two arrays of hashes.

Is "location_id" numeric ?
If so, you can make lookups considerably faster by using an array:

my @filters_locations; $filters_locations[$_]=1 for map {$_->{location_id}} @filters_info;
If it is not numeric, make %filters_locations a hash.

Later, you can lookup the selected location by indexing into @filter_locations (or the hash).
