Yes and no ;) In fact I'd rather have 'f' does a 'f'orward of current
thread/message rather than refine the current search.

Why not just have a unique function then if, in the end, there is
another global search ?

I would propose to have 's' (when in a notmuch-search buffer) to do what
pressing 'f' does today -i.e appending a 'and' and bind C-u s RET to do a whole brand new global
search.

What aout that ?
