Yea i've seen this many times with price comparison engines, i even used to work for one and was head of search back then. We had to actually "tune/down-weight" phone accessories vs phones. Ppl typing in "iphones" wants "iphones". Ppl typing in iphone cases wants "iphone cases". The rudimentary problem is both of the text tokens are in the titles and are popular products. "precision vs recall vs popularity/sorting". We had a similar but lesser problem with books (the titles are so vast and ambiguous). Lol you get a book called 'iphone'. The leading ecomm platform in my country (s.a) has this book problem in search results and mm-tokens still. Looking at you T..A..L ;). End of the day, search is hard and personal.
