Amazon illustrates a test case I have been overlooking.
If you search for
herb alpert i feel you, you get no results:
Which is really weird, because I’ve bought Herb Alpert’s I Feel You. And I just successfully found it. However, I previously searched for
i feel you herb alpert:
It looks like in the first case, when the artist’s name came first, Amazon incorrectly “corrected” the name to herb albert before conducting the search and then returned me an erroneous result.
So now in my test cases for searches, I have to alter the order of the search terms to ensure they return the same results.
