Search folders using custom meta-data

[Clock1932]

It is possible to attach a meta-data template to a folder, but it is not possible to search folders based on these meta-data attributes.

Use case:
I assign meta-data template to a specific folder. One of the attributes is the employee responsible and the due-data of the project (folder).
It would be a nice addition if I was able to do a search for all projects assigned to a employee or to search for all the folders that have a deadline within a specific period.

I think this functionality can be added within the folder-search-tab or as an extension on the parametric-search-tab (currently limited to file objects)
