By default, search commands perform @dfn{lax space matching}:
each space, or sequence of spaces, matches any sequence of one or more
whitespace characters in the text. (Incremental regexp search has a
separate default; see @ref{Regexp Search}.) Hence, @samp{foo bar}
matches @samp{foo bar}, @samp{foo@w{ }bar}, @samp{foo@w{ }bar}, and
so on (but not @samp{foobar}). More precisely, Emacs matches each
sequence of space characters in the search string to a regular
expression specified by the variable @code{search-whitespace-regexp}.
For example, to make spaces match sequences of newlines as well as
spaces, set it to @samp{"[[:space:]\n]+"}. The default value of this
variable depends on the buffer's major mode; most major modes classify
spaces, tabs, and formfeed characters as whitespace.

matches @w{@samp{foo bar}}, @w{@samp{foo@ @ bar}},
