In Google searches (and many other kinds of searches
like grep/Regular Expressions) it means: OR
You can type "OR" at Google but (last I cheched) the
CAPITALS were required to make sure it was used as
a command and not a search term.
Also possible: -Minus sign in front of a term or phrase
to disallow pages containing that item. Highly useful
if you are looking for information where synonyms are
getting in the way, e.g., gravy boat -lake -ocean -power
The above might be better expresses as "gravy boat" in
any case, forcing the phrase and not just the two separate
Also, you can put * (wildcard) in a quoted expression,
e.g., "windows * server" would match 2000 or 2003 or
even NT server.
~synonym match, e.g.,: "active directory" ~error
(probably matches things like problems, failures, etc.)
Site is one of the BEST criteria, although it might not
always be necessary when using terms that are so
Microsoft specific as "Group Policy" or "Active Directory".
site:gov site:whitehouse.gov are both legal.
You can even go very specific, e.g., site:msdn.microsoft.com
Highly useful when searching UNIVERSITY sites for things
provided by specific individuals, such as professors.
