Yep worked for me now, strange.

I searched for strange weapons and my trade showed up but still they go down in the results because I mostly find ususal strange weapons this way.

I don't think it's working like it's supposed to do.

I'm currently offering 3 Australiums in one trade but when I try to search for one I'm getting this message

"We couldn't find any matches for your search, sorry. If you didn't enter any items on either side, you'll never get any matches. If you want to do a wildcard search for any item with a certain attribute, then select the "Wildcard Item" and give it filters."

Here is the trade link: http://www.tf2outpost.com/trade/17636106

Why can't I find any Australiums / my offer?
