The issue is fixed for me but I'm not sure about you guys. All I did was leave it alone until the next day and when I got back on it worked again. Hope this helps anyone

Whenever I search for items such as DoN or Keys i get
"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."
But I've put items on both sides and I've also searched the items by themselves. This has happened with every items i put in to search and it gives me the same response. It was working just fine earlier but it just shutdown on me.
