help with GREP command

[luigistic]

Hello Community,
I'm a newby in linux's world.
I need a help with a command.

If I search the word google in the file.log I have many, many results that can't be listed in a page. Than, if I scroll back withe the mouse, I can't see all of them.

1) How can I execute the grep command in order to see all results?
2) I can I exit to that command?

Thanks

grep -i google file.log

This and much more is in man grep.
