It is quite unclear to me what @ symbol do when searching (
http://developer.ebay.com/DevZone/finding/Concepts/FindingAPIGuide.html). I thought that the resulting product must match except for @x words. Apparently not. When I search for keywords "Grab and Lift Silicone Tong Waffle Spatula Easy Grab NonStick No Scratches", it gives me one result. However "@1 Grab and Lift Silicone Tong Waffle Spatula Easy Grab NonStick No Scratches" gives me no results. Thanks a lot for clarification.
@1 finds two of three words from a list of three words @2 finds three of four words from a list of four words It's not extensible to any length string and you have to use a + before the additional word list
