Since TimC gave a good explanation, I won't attempt to repeat it.
However, if you're wanting to do Boolean-logic pattern matching, please
check out LogiPat, available at my website:
http://mysite.verizon.net/astronaut/vim/index.html#LOGIPAT
or at
http://vim.sourceforge.net/scripts/script.php?script_id=1290
Examples:
:LogiPat "abc"
will search for lines containing the string "abc"
:LogiPat !"abc"
will search for lines which don't contain the string "abc"
:LogiPat "abc"|"def"
will search for lines which contain either the string
"abc" or the string "def"
:LogiPat !("abc"|"def")
will search for lines which don't contain either
of the strings "abc" or "def"
:LogiPat "abc"&"def"
will search for lines which contain both of the strings
"abc" and "def"
:let pat= LogiPat('!"abc"')
will return the regular expression which will match
all lines not containing "abc". The double quotes
are needed to pass normal patterns to LogiPat, and
differentiate such patterns from boolean logic
operators.
