This is the search function, right? https://subeta.net/wishlists.php/search

It's working correctly; for instance, I just tried searching some of the new MC center items and they came up with results.

I think it's just that the auto-complete suggestion is not working for new items. If you type the full name of the item and click the button to search, it still works everywhere. It's just that typing the partila name doesn't cause it to suggest the full name for newer items. Does that sound more accurate to what you're experiencing?

You can, there's just none in trades at the moment.

The search bar's auto-suggestion for item names has been fixed, and should now update correctly with new items :)

Thank you again for reporting this issue!
