Yes, there is, it's http://man.cx/. It aims to have all man pages in one site, also in multiple languages. The anchors are unfortunately not named, but numbered: for example http://man.cx/printf#heading1 will take you to the first heading of the printf man page. Still I think it's better than without anchors ;)
PS. Add the site to your search engines, then you can simply type man printf in your address bar, and it will take you to the correct page, super awesome!
The default man pager is less. If you look at less's help (press h while in it), you'll see:
SEARCHING
/pattern * Search forward for (N-th) matching line.
?pattern * Search backward for (N-th) matching line.
n * Repeat previous search (for N-th occurrence).
N * Repeat previous search in reverse direction.
ESC-n * Repeat previous search, spanning files.
ESC-N * Repeat previous search, reverse dir. & spanning files.
ESC-u Undo (toggle) search highlighting.
&pattern * Display only matching lines
---------------------------------------------------
A search pattern may be preceded by one or more of:
^N or ! Search for NON-matching lines.
Or in man less:
/pattern
Search forward in the file for the N-th line containing the pat‐
tern. N defaults to 1. The pattern is a regular expression, as
recognized by the regular expression library supplied by your
system. The search starts at the first line displayed (but see
the -a and -j options, which change this).
Certain characters are special if entered at the beginning of
the pattern; they modify the type of search rather than become
part of the pattern:
^N or !
Search for lines which do NOT match the pattern.
So, a pattern of just ! is an empty pattern (which matches anything) negated - so nothing will match it.
You'll have to escape the significance of ! at the start of a pattern, by either using a backslash (\!), or otherwise making it not the first character of the regex (/[!], for example).
The other way is to use grep:
$ man find | grep !
with `-', or the argument `(' or `!'. That argument and any following
! expr True if expr is false. This character will also usually need
Same as ! expr, but not POSIX compliant.
The POSIX standard specifies parentheses `(', `)', negation `!' and the
find /sbin /usr/sbin -executable \! -readable -print
find . -perm -444 -perm /222 ! -perm /111
find . -perm -a+r -perm /a+w ! -perm /a+x
-perm /222 or -perm /a+w) but are not executable for anybody ( ! -perm
/111 and ! -perm /a+x respectively).
find . -name .snapshot -prune -o \( \! -name *~ -print0 \)|
