Before the change, there were two ways to do search in Emacs UI:
search widget in notmuch-hello buffer and `notmuch-search'
function bound to "s".  Internally, notmuch-hello search widget
uses `notmuch-search' function.  But it uses widget field input
instead of minibuffer.  Such duplication is a major issue for
notmuch-hello usability: search interface is inconsistent and
lacks features that are available in minibuffer (e.g. history and
auto completion).  Some of these features may be relatively easy
to implement for notmuch-hello search, others would be much more
tricky.  So to avoid duplication, make UI more consistent, bring
notmuch-hello search to feature parity with the minibuffer
search, the patch replaces notmuch-hello search widget and with a
button that works the same way as "s" key binding.
