What did you search?  This information is in the Emacs manual, which
is available on-line from within Emacs.  Type "i C-x b" inside Emacs's
manual, and you will be led to the section which explains the command
"C-x b", and has a cross-reference to the section about completion.
(Note: You should type the literal characters C - x b after `i' in the
above command, not press Ctrl and hit x as usual.)

Type `?' after "C-x b", and Emacs will pop a window with possible
completions.
