How to show the complete syntax tree

How to show the complete syntax tree

Hi,
    The command I can find in the manual to show the syntax tree is
(org-element-parse-buffer). However, when the structure is output to the
buffer, by using the commands C-u M-: (org-element-parse-buffer), it seems
that only the part up to a certain depth is printed.

For example, if the current org buffer has the following content:

#+TITLE: Hello World
Hello World!
* HEADLINE 1
** Sub-topic
+ ItemA
+ ItemB
- Item1
- Item2
*** Sub-Sub-topic
\begin{equation}
    \label{eq:test}
    Bx=b
\end{equation}

When apply C-u M-: (org-element-parse-buffer),  the sub-sub-topic level is
completely omitted in the printout:

(org-data nil (section (:begin 1 :end 35 :contents-begin 1 :contents-end 35
:post-blank 0 :parent #0) (keyword (:key "TITLE" :value "Hello World"
:begin 1 :end 22 :post-blank 0 :post-affiliated 1 ...)) (paragraph (:begin
22 :end 35 :contents-begin 22 :contents-end 35 :post-blank 0
:post-affiliated 22 ...) #("Hello World!
" 0 13 ...))) (headline (:raw-value "HEADLINE 1" :begin 35 :end 174
:pre-blank 0 :contents-begin 48 :contents-end 173 ...) (headline
(:raw-value "Sub-topic" :begin 48 :end 173 :pre-blank 0 :contents-begin 62
:contents-end 173 ...) (section ... ...) (headline ... ...))))

What's the recommended way to show the syntax tree? Thanks.

Following up in outorg, I evaluate this in the *outorg-edit-buffer*:

#+begin_src emacs-lisp :results raw
(org-element-parse-buffer 'object)
#+end_src

#+results:

(org-data nil (headline (:raw-value --text follows this line-- :begin 1
:end 1604 [...]

>  :post-blank 0 :parent #3))
> Bx=b
>  (latex-fragment (:value \end{equation} :begin 597 :end 611
>  :post-blank 0 :parent #3))

Yes, as Nick explained there are variables that control this.

My eyes sometimes like this approach to viewing lisp objects:

#+BEGIN_SRC emacs-lisp
(pp-to-string (org-element-parse-buffer))
#+END_SRC
