Well... yes! I made a series of in-depth analyses of Google counts. They
are totally bogus, and unusable for any kind of serious research.
There is a summary here :

I applied the same criteria to Yahoo, and it seems that their results
are (if not sincere) at least credible and usable for research (I mean
that if they are inflated for marketting reasons, which is always
possible, it seems to be in a proportional way).
