Nothing important, I was just reading documentation of radomly choosen
commands. But the same happens on a number of commands.

Really I am searching for _command_ help: "C-h F replace-string" gives:
Next: Regexp Replace,  Prev: Replace,  Up: Replace
(emacs)Top > Search > Replace > Unconditional Replace

| 19.9.1 Unconditional Replacement
| --------------------------------
|
| `M-x replace-string <RET> STRING <RET> NEWSTRING <RET>'
|      Replace every occurrence of STRING with NEWSTRING.
|
|    To replace every instance of `foo' after point with `bar', use the
| command `M-x replace-string' with the two arguments `foo' and `bar'.
| Replacement happens only in the text after point, so if you want to

| (see Mark).

With "C-h F format-decode-buffer", I get:

Can you recreate this issue in an emacs -Q session? On my emacs version
(25.x), C-h F format-decode-buffer returns this node: (emacs) Enriched Mode

I do not know if that piece of information existed in emacs 23.x info
manuals.

Exactly the same as before. I forgot to mention the message buffer
reports: "Info-goto-emacs-command-node: Couldn't find documentation
for format-decode-buffer". I suppose it does not give any information
more than before...

Well then, that is self-explanatory :)

As of the emacs version you have, probably the info manual did not have any
references to format-decode-buffer.

Please update to the latest stable release and try again.
I would even recommend updating to the second RC of the to-be-released
emacs 25.2 very soon:
http://alpha.gnu.org/gnu/emacs/pretest/emacs-25.1.91.tar.xz

See here to get the latest stable release (25.1) for your OS:

Emacs 23.x Info manual doesn't mention format-decode-buffer.

OK. As others have noted, docs for later Emacsen are more complete.
Updating recommended. In the meantime you might want to try C-h f
(small "f"), which leads you to the function's docstring. Pretty
terse, but most probably existent.

Thus can I get to the same conclusion for every similar situation? I
mean, whenever I cannot find info for a command, is likely because
such documentation is not bundled in the emacs package version I
installed? Non possibilities of missing external packages, or
unsatisfied dependencies?
In the meantime I am compiling version 25.1. Thank all for answers
