Google will search for several punctuation marks and special characters:
~ the ampersand [&]: Google will search for [barnes&noble] or [barnes &
noble]
~ the underscore [_]: Google will search for a phrase such as
[public_records.doc] or even more specifically [public_records.html]
~ the dollar sign [$], used with a number, for example [$100]
~ the sharp [#], for example [F#]
~ the slash, but only when used in the search [I/O]
~ While Google will not actually search on a plus sign, the search engine does
recognize the difference between searches for [c], [c+], and [c++]

effective in many cases. These query modifiers can be used in simple search in the
following syntax or on the advanced web search page using the appropriate menu
options. The query modifiers Google supports are:
