Getting number of hits from Google

[neocortex]

Hello!
For quite some time, I am looking for a solution to the problem of
getting number of hits for a list of, let say, 200-300 words, from a
search engine. I would prefer Google, but this seems not possible. I
tried with the PyGoogle (from http://code.google.com/p/pygoogle/), but
it stops delivering number of hits after 20-50 words.
Please, can anyone help me with this. I am starting to be desperate.

Sincerely,
PM
