Download Mathematica documentation in local

Questions

1

I just installed a raspberry pi in my lab, where I use it insulated from the network.
Since I find the use of Mathematica priceless, I wanted to know if it is possible to have access to the documentation in local: I read different estimates on the size of Wolfram Language & System Documentation Center - between 200MB and 1.5GB - but in any case well inside the space available to modern SD cards.

First question: can I simply wget reference.wolfram.com/language, or is it considered bad form since it hammers the website?

Second, I read somewhere that somebody tried it already and the docs are perfectly accessible - save for the search function. Do you know if this is the case, and if it is possible to recover that functionality?

thanks for the help

If you have Mathematica, it is just stored as a bunch of notebooks in the directory (on mac):

“/Applications/Mathematica.app/Contents/Documentation/English/”

Just run NotebookDirectory[] in the documentation to find out the location of the notebooks.

I’m not sure if it is allowed to share these though; on one hand Mathematica surely has copyright, on the other hand the documentation is also freely available online…

well, we have the license in the institute where I work, so that is not a problem…

I must say that I seriously under-estimated the space required:

# du -h -d 1 /usr/local/Wolfram/Mathematica/11.1/Documentation/English/
221M    /usr/local/Wolfram/Mathematica/11.1/Documentation/English/Index
77M     /usr/local/Wolfram/Mathematica/11.1/Documentation/English/SpellIndex
4.4G    /usr/local/Wolfram/Mathematica/11.1/Documentation/English/System
76M     /usr/local/Wolfram/Mathematica/11.1/Documentation/English/Packages
4.7G    /usr/local/Wolfram/Mathematica/11.1/Documentation/English/

I still do not have any idea how to open it from my raspberry however: the index dir contains just these 3 files…

# ls /usr/local/Wolfram/Mathematica/11.1/Documentation/English/Index/
_d.cfs  segments.gen  segments_t

and the links between help pages do not work, reporting not found on links of this kind: paclet:ref/<function name>
