I suppose there migt be possible to remove Google from action=edit things in the
robot.txt? That must be the most effective global way of preventing Google to index action
pages. -- Dan Koehl
Checking a bit more, I get the impression that google
does not save the
contents of pages with "noindex" in their robots meta, but does remember
their URL. This time that caused a hit because the text searched is also as
a word in the URL.
