If you set your filters to the following: Choose a class or slot (since it's required), Set to Augmentations Only, Exclude Crafted Items... you receive no recent augments in the search, other than a couple of emblems and one or two augs.
It's looking to me like most of the Augs (aka Slippery Slimerock) are classified wrong (I think this aug is classified as 2hd Slash?). It's kinda annoying me too, I payed for prem membership so I could find some augs etc but I can't :(
