Thanks for taking time to implement this proof of concept!

I think that it is a very good idea for Org core to support search terms
in file links that are handled by Free Software.

Moreover, I think that we should, by default, auto-detect and use Free
Software to open file links, when such software is installed on user
machine (unless the user explicitly instruct otherwise).

I see Free Software support as dedicated files like ol-evince,
ol-okular, etc. The file functionality and common function may probably
be factored out into ol-file library.
