+@vindex isearch-resume-in-command-history
+ Incremental search does not, strictly speaking, use the minibuffer,
+but it does something similar. Although it behaves like a complex command,
+it normally does not appear in the history list for @kbd{C-x
+@key{ESC} @key{ESC}}. You can make it appear in the history by
+setting @code{isearch-resume-in-command-history} to a non-@code{nil}
+value. @xref{Incremental Search}.
