Tip #3a
Don't waste time with the Shift key. Upper or lower case doesn't matter with Google.
"New York" or
"new york" will yield the same results.
Tip #3b
Use spaces to separate words. The common words
in,
to,
of etc. will be ignored. You don't have to use
AND to indicate that you want both words included - it's done automatically.

There is one major exception to both tips #3a and #3b: the word
or . If you use lowercase
or it will be ignored as a common word. For example,
dogs or cats will return
dogs & cats ,
dogs, cats,
dogs and cats ... But, if you use the uppercase
OR , as in
cats OR dogs you'll get pages on dogs and pages on cats, etc.
