tool to see # of websites for a keyword in google index?

[Kikos]

hi is there a preferably free, otherwise paid, tool to see # of websites for a keyword in google index?

like when you google Happy Holidays it says
About 60,600,000 results (0.23 seconds)

and if you do intitle:"Happy Holidays" it says:
About 2,260,000 results (0.23 seconds)


I need to be able to feed a long list of keywords (thousands) and for whatever tool to tell me such numbers as above


Thank you!

When you enter the keyword in double quotes this means ‘x’ number of pages are ranking for exact keyword.

Where as, keyword without quotes is broad search which means other related pages may also appear for this keyword.

Hi Rebecca, thanks, but I did not ask what broad or exact means....
I asked for a tool which can generate this data for hundreds of keywords at a time
