I don't think you can, as ebay's stats are fairly generic and mostly give you an overview rather than any real insight into traffic sources and behaviours etc.
The best I can suggest is trying a keyword search or two for your item and checking whether eBay refines the search automatically to a specific category (they will do this for some searches, I've noticed, eg if you search for 'silver chain' it might narrow the search automatically to the fine jewellery category rather than search site-wide).
