How to find Preset (.duf) in Smart Content

Is there a way to find out:

1) If a preset file (.duf) is in smart content; and if so:

........2) Information from that asset like: Type and Category?

I tried searchForAssets in DzAssetMgr, but it errors if I use the full path. If I just use the preset file name that really will not help if, for example, a pose preset that is named 01.duf.

And as I'm playing with searchForAssets, it is only working in the Script IDE, in debug, and if I step to it. All other ways are returning empty :(
