Amazon uses the same system even for very specific technical items. I buy Hardware or car parts sometimes and I go search on Amazon. Even though I'm specific with my search, it pushes results that are not correct and I don't notice. In the past I ordered items that were wrong because they were blended in with the right results. Of course they're useless for my needs so they are returned. Adding another cost to the seller I suppose.
Note: I quit Amazon couple years ago and after a couple weeks when I was in to look for items, not by, It offered me the $180 subscription for $9.99 so I took it for emergencies in the past year. I got better with my emergency needs so I am not even using it almost at all.
