You say it, not yet. I'm not sure it would make sense to publish all the source code, more than the basic one, on Github, if it is an experimental alpha product, in intensive development and improvements and changes every few days. It is enough for me that it really respects privacy and, even in alpha, it is extremely practical.

Anyway, as you can see in my screenshot above, that I use apart a lot of diferent search engines and specific site searches, depending of what I need to search. I use Andi as first search for the daily common use, for which is normally enough, giving me direct answers and not only a list with not related results.
