Notation of the stipulation

Quite recently I found some twomovers with some additional informations in a stipulation like #2 vv, #2 v, #2 v..., #2*v.
I search in the internet, but I didn't find any information about this.

What does these options in a stipulation means? Are there still another options important to know?

Those symbols are indespensable for the modern 2# (somewhat less so for
other problem categories but that's just a matter of time).

v = Seek a try (v=Verführung, the German word for try) or you won't
understand what the composer wanted to show!
vv = Two tries etc.
(v) = No sane person would actually try this try but still,
if you don't, you won't etc. :-)
* = Look at the set play etc.
EDIT: . = Not sure, either set play or many many v.

Let me disagree with this explanation:

(v) = No sane person would actually try this try but still...

I would rather say "normal chess composition initiate" instead of "sane person". I have seen many sane chess players trying these "insane" tries as they are in fact often strong moves in the normal chess sense, although they are considered no-no by chess composition standards - checks, captures, flight-taking etc.

There is no sane chess player! Chess just keeps insane people sane!

@Juraj: The snipe wasn't against "strong" moves not
expected by a problemist to be the key anyway, but
rather against those with "obvious" refutations.
(Corollary: The stronger the solver is, the better
the composer has to be :-)
