Back again. Well, you have given me a nice link. I have it as my main engine in Firefox and now I am looking to fix my Android in such a way, that it uses it there also as primary search tool. Reverse image search is a bit of a bugger, but my Tinyeye plug in and a little Google will suffice for now.
They seem open for suggestions at Qwant, so I might start digging the forums. :-)
Right on! Compared to Google and TinEye, near as I can tell, everything else is kid stuff. When even Wolfram Research is finger painting by comparison, there's no shame in using Google Images. There's computer vision, and then there's understanding.
