Best wishes to your friend. I have noticed Amazon's poor book search results too. If you search "fortran" in books you see some irrelevant content (the biography "When Fortran was Queen" is not what people are looking for) on the first page of 24 books, and the quality falls after that. There would be probably be volunteers who could curate common Amazon book searches in their area of interest. I think this would help Amazon's sales, because I doubt that many people buy the dumb notebooks mentioned.
