Search function, add another function?

[Q?]

Tagging movies with director's names.
i.e. searching for Stanley Kubrick only a bd collection shows up.
It could be easier searching for movies by directors too, if you have a
favourite director and if you wanna know how many movies are released
on blu-ray by a certain director.
Too much work? not needed?
Thanks in advance.
and by the way... did I mention blu-ray.com 's?
