You actually want Amazon to show you different search results?
If I'm starting a new hobby or wanted to buy a present for someone with different interests, I would be very annoyed if results were hidden from me because of a name clash with a product from my purchase history.
A good product search isn't personalized, and doesn't try to predict what I want. It just shows the results in a sensible manner, and lets me use categories and keywords (in addition to user reviews, price, availability, etcetera) to filter the results.
Then you may have found a bug in their search algorithm. On Amazon.de I get guitar string and books (and some sort of cologne), and when I click on 'Fremdsprachige Bücher' (for example), I get only books on programming in Elixir.
