Open Source Document Management System | OpenKM

Hello,
is it possible to browse documents by property group? Or to sort by them?

For example, I have a lot of documents with the property group Customer and I want to view them all sorted ascending by this property.

And one more question - how to correctly search by property group? Is the onle way to switch to metadata tab, add property group and enter query? Or maybe it's possible to search through Basic tab?

Property group only can be show in advanced tab.

I take note about your purpose about navigate across metadata, seems interesting. I'll make some browser in navigator like exists for categories, I've added the ticket at http://issues.openkm.com/view.php?id=1836
