Searching across line breaks

Searching across line breaks

[spinner]

I've got text with carriage returns (CR) ending lines in my LaTex documents.
isearch does not work for word strings with CRs separating the words. For
instance, isearch on 'George Washington' will not find:
George [CR]
Washington

I've looked online for a solution and found one source that describes the
issue but I'm confused what the customization to the
search-whitespace-regexp variable should be.
http://stackoverflow.com/questions/6029010/isearch-across-line-breaks

This link describes the confusion. I'm a new to emacs and can't figure out
the variable settings.
http://lists.gnu.org/archive/html/bug-gnu-emacs/2011-05/msg00427.html

Again, what is the proper setting in search-whitespace-regexp to search
across line breaks with carriage returns?

M-x isearch-forward-regexp RET

should enable the right thing here.

This did not work for me. 
According to the links in my OP, some settings need to be customized to make
search-whitespace-regexp work across CRs (and other separators). But as I
said I find the documentation on this customization confusing. C-h v
search-whitespace-regexp

George[\r\t\f
]+Washington

should find any name separated by blanks, tabs, newpages, cr, newlines

the newline-expression in the regexp must be typed \C-o inside the 
minibuffer, ie inserted literarly

Shouldn't it be C-j or C-q C-j? C-j is dec 10, oct 12, hex 0A, UTF U+000A LINE FEED (LF). (C-o is SHIFT IN.)

Hm, de facto that works for me, I'm doing \C-o here. Which was hard to 
figure out at the beginning with Emacs BTW.

No explanation so far, just experience. Might \C-o from minibuffer be 
translated differently by Emacs?

Maybe someone else can comment.

Thanks pointing at that,

Andreas

`C-h r' `C-s C-q C-j' `C-s':

,----[ (info "(emacs)Minibuffer Edit") ]
|    Since <RET> in the minibuffer is defined to exit the minibuffer, you

`----

So, both of you are right.

FWIF, I learned `C-q C-j', because it was easier to remember once I knew
what `C-q' does, thusly avoiding the "hard to figure out at the
beginning" bit.

Is there a variable which can be set which toggles on word-mode for C-s
and C-r?
