The Search function is a field where you can type a word and
it will return topics in which that word is located. So when you
state that is what is WAS and then say "NOW it seems that it's just
a listing of every word in the Help and the number of occurrences"
I can't quite see the difference.
It is a listing of all the words in the help, that is pretty
much what any search is although they do vary in their ability to
deal with multiple words and so on.
RH has a default Stop list and you can add to that. Click
File | Project Settings and then click the Advanced button. You
will see a list of excluded words that you can add to. That is the
approach rather than hacking the list produced when you generate
the help.
