Part (a) I specifically want to know how many times (daily or weekly)
the words "Free Software" are used as search words in the big "G".
Part (b) If it is possible how can I find this sort of information
myself for other searched words such as (say) "Portable Printer". 
End of Question Part (a) and Part (b)

Additional Comment:
I note that prior to writing this question I keyed in "Free Software"
and could see from the top of the page that there are 16,200,000,000
pages (or entries) with those search words appearing on them. So as I
am "magically" told there are sixteen million pages with the words
*Free Software* on them. Can I ever so quickly and magically find out
how many times people search these two words daily? (or any other two
words for that matter) A good tip will be added for a complete Answer
to this question (Part A & B).
