I haven't read it and I want to though I don't feel like ordering yet another book as I have done so a few times in the past weeks.
I found a pdf which seems to be the book but I also found that other versions are longer/have more pages.
Anyone that can provide me with a link?
Thanks heaps for that. I saved your comment for future use. Ya I use yandex regularly, but not the other sites you mentioned.
I also recommend looking at the list of search engines and websites that SearXNG supports in the link I gave you. It helped me discover many search engines I wasn't aware of.
