I wanted to search what $? means in perl. If I use regular google
search I don't get any relevant results. If I use google code search I
get only code snippets. What is really want is that I want to search
$? among the documentation regarding perl.
Please see if this feature can be added or if there is already a way
of doing this, please let me know how

Documentation isn't code. Shouldn't you be doing a regular google
search for that?

I did a quick search for "perl" + "$?". The fourth hit on the page was
a doc-page titled "PERL - Special Variables" where you can see that $?
is documented as:
The status returned by the last pipe close, backtick(``) command or
system operator. Note that this is the status word returned by the wait
() system call, so the exit value of the subprocess is actually ($?
>>*). $? & 255 gives which signal, if any, the process died from, and
