Amazon’s fuzzy search

I just made the mistake of entering “paco bello” in the Amazon.co.uk search box. The results say:

We found no matches for “paco bello” . Below are results for “pack bell” . If you prefer, you may try another search.

And neither “nauta” nor “doctor grillo” yielded any results on Amazon. And no results on iTunes music store, either.

This confused me so much, that I went and bought Take That – Greatest Hits. Someone please get me a new brain for my birthday. Pretty please?
