There is a vendor search kiosk located at the entrance of Folkvang that will search player vendors for a particular item. Simply use it and search for a partial name of an item.
Only one person can use the vendor search kiosk at a time.
Registering your Vendor
Vendors are automatically searched if they are within the marketplace of Folkvang, Zarkesh, Eastfall, Portsmouth and the town of Valles. If your vendor is not within these areas (such as at your house) and you want players to see what they are selling, you will need to register the vendor with the kiosk. Simply bring up the kiosk menu, go to your vendor and then select the Register button. You will have to do this for every vendor you need registered.
