  The Emacs search command is "incremental".  This means that the
  search happens while you type in the string to search for.

  The command to initiate a search is C-s for forward search, and C-r
  for reverse search.  BUT WAIT!  Don't try them now.

  When you type C-s you'll notice that the string "I-search" appears as
  a prompt in the echo area.  This tells you that Emacs is in what is
  called an incremental search waiting for you to type the thing that

  "failing".  C-g would also terminate the search.

  If you are in the middle of an incremental search and type <DEL>, the
