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