Completion with M-x describe-variable (aka C-h v) in effect searches all
Emacs Lisp libraries to find completion candidates, while
customize-variable just examines loaded libraries.  Calling M-x apropos
just loads the library (you could also use e.g. M-x load-library RET
apropos), you don't need to enter search terms to subsequently get
customize-variable to recognize options in the loaded library.
