Thanks for pointing this out.  But boy is it complicated:

I have:

   org-occur-case-fold-search is a variable defined in `org.el'.
   Its value is t

   Documentation:
   Non-nil means `org-occur' should be case-insensitive.
   If set to `smart' the search will be case-insensitive only if it
   doesn't specify any upper case character.

and indeed, if I use

   M-x org-occur <RET> FOO

in my FOO/foo buffer, both instances are found.

But it does not seem to apply to multi-occur, which 'C-c a /' is said
to use: both 'C-c a /' and 'M-x multi-occur' for 'FOO' only list
'FOO'...

From my (user) point of view, I would expect that what is supposed to
be a regexp behaves like a regexp, and in a consistent way for all
cases (with 'C-c a s', when filtering with
org-agenda-filter-by-regexp, etc.).  I would even expect a regexp
search within an Org buffer to behave exactly like a regexp search
within a plain emacs buffer, but I would understand if this not
reasonable to ask for.

Regards,
a.

PS: in the org-occur docstring:

   org-occur is an interactive compiled Lisp function in `org.el'.

   (org-occur REGEXP &optional KEEP-PREVIOUS CALLBACK)

   Make a compact tree which shows all matches of REGEXP.

   The tree will show the lines where the regexp matches, and any
   other context defined in `org-show-context-detail', which see.

the last sentence above looks grammatically/syntactically funny to me.
Maybe this is because of my insufficient level in English -- I just
don't understand what "which see" is supposed to mean.  If the English
is indeed correct, maybe a reformulation would be in order, for the
sake of non native people.
