Is META data searching possible using Gallery 2/3?

Hi there,

Does anyone know if it is possible to search using the G2/3 interface for META data in images or is it only keywords that are manually assigned in Gallery?

I would like to use Gallery to create an archive of my photos. Photoshop/Bridge allows me to put the relevant tags/meta data in per photo and to be able to search that would be perfect - since then the photo details aren't linked to Gallery and can be exported for other uses etc.

Many thanks
