grep, tags and dired search to hard to find in Info

[Lennart Borgman]

If you look at the "(emacs) Search" node in Info there is no information 
about find-grep etc, tags searching or dired searching. Information 
about this is in the last paragraph of the subnode Other Repeating Search.

I think it would be much easier to find and more logical if this last 
paragraph was moved to the Search node.
