Yes, I too had to check it out. Apparently Google pays no attention to apostrophes. Wisely, because there are three reasons by people use the apostrophe

1. To show possession - My dog's dish

2. To indicate that letters are missing - I can't find it!

3. To mitigate evil from a word that scares us. Your English teacher probably didn't teach you about this, but if you've ever seen a sign for "Potato's - 1.29/pound" or "tomatoe's", then you've seen this philosophy in action.

The people at Google have figured out that apostrophes are unreliable, and they seem to ignore them.
