This could be a useful thing, but before we decide to install it, we need to check some crucial nontechnical issues. * The moral issues. Does Xapian include any nonfree software? Does it depend on the presence of any nonfree software? Does Xapian use some web service? * The legal issues. Assuming Xapian does everything with free software, is all that software under GPL-compatible licenses? If not, we need to look at how the non-GPL-compatible software connects with the GPL-covered body of Emacs and its add-ons. Depending on that, it might be ok. See https://gnu.org/licenses/license-list.html to check whether a license is free, and whether it is GPL-compatible. -- Dr Richard Stallman (https://stallman.org) Chief GNUisance of the GNU Project (https://gnu.org) Founder, Free Software Foundation (https://fsf.org) Internet Hall-of-Famer (https://internethalloffame.org)
