Hierarchies and system for tags and file names when working with CC library

Hi,

I was wondering if any one of you has experience working with CC Libraries and having to name/tag all items in a way that is easily searchable any time and by anyone.

I am working on different scientific videos accompanying them with illustrated items which I use, edit and reuse regularly.
So far I have up to 50 Libraries with up to 2300 items, and we are about to expand our Team of Illustrators which will also have to use the libraries.
As far as I could tell from other discussion panels, there is not yet a filter system that would allow an easier way of sorting through, correct?

So I was wondering if there are any ideas to work around this issue by name tagging, or similar functions? Using different, categories (e.g - all my items concerning technology are named, "technology,..." but then also more specifically "technology, spintronics, electrons, magnet...") As you can imagine that is pretty time consuming and requires a lot of discipline and still does not allow to clearly arrange all assets.

That's the best I could come up with though so far and I was hoping some of you running into similar issues have come up with better solutions?

Obviously the development of a proper tagging function in the near future would be highly appreciated.
