Ask HN: Why is search on Amazon so bad?
2 by arcturus17 | 3 comments on Hacker News.
I have noticed in the last couple of years that search results on Amazon have become horrendous. Often I am looking for highly specific items, and Amazon will recommend many items that have nothing to do with them in the first ten results. For example, I have just looked into "weightlifting shoes" and the THIRD result was a cycling shoe. This is in the Spanish store. After checking the American store, results are slightly better (the Spanish store is truly atrocious), but there are many bad results within the first twenty or so results. Does anyone know why this is happening?
