Run /usr/libexec/locate.updatedb as root; that'll do it. The database
is usually updated weekly.

The same way you can escape special characters from the shell by
putting a \ in front of them, you can escape special characters from
find:
-name pattern
True if the last component of the pathname being examined
matches pattern. Special shell pattern matching
characters (``['', ``]'', ``*'', and ``?'') may be used as
part of pattern. These characters may be matched
explicitly by escaping them with a backslash (``\'').
