Re: How to make emacs clear search when pressing Ctrl+g?

[Joseph Garvin]

The issue is that after pressing Ctrl+g multiple times to get out of
the search, if I hit Ctrl+s to start a search again without first
moving the cursor, it still remembers the search. It doesn't matter
how many times I hit Ctrl+g first.
