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).
