Documentation

If non-nil, a space will match a sequence of whitespace chars.

When you enter a space or spaces in regexp incremental search, it will match any sequence matched by the regexp defined by the variable search-whitespace-regexp. If the value is nil, each space you type matches literally, against one space. You can toggle the value of this variable by the command isearch-toggle-lax-whitespace, usually bound to M-s SPC during isearch.
