There are so many ways a prospective buyer can search and so many different keywords they can search for that it is almost meaningless which is proven by your post, different search criteria produce different results.

Not exactly - clicking through to a specific category from the main eBay menu and clicking through to the specific category that a listing is in from that listing is exactly the same search criteria, so should have yielded exactly the same results (give or take a few, certainly not ~700).

@suitcase, I just went to the same categories and got 865 results from the eBay menu, and 866 after clicking it from a listing, so could have been a temporary glitch - I notice very similar anomalies in my searches from time to time, but usually a page refresh or trying the search again will bring up the correct results (well, I suppose here 'correct results' probably means 'the most eBay are willing to show me at any one time' :^O ).

Not so much a laughing matter when people searching get those kinds of results and are none the wiser about what they're not seeing, though. 😕
