Deepsearch is a privacy enhanced search engine from Tsignal

I found it interesting that another company has taken on the "full stack" problem of providing a search engine. I found their FAQ also quite interesting : https://deepsearch.tsignal.io/static/faq?hl=de

4 billion pages in the index is a good number, it hits the major sources if you don't index things like all of Amazon or Yelp. A better number is 10 billion, that is pretty much usable by everyone all the time, especially with smart pruning of automatically generated sites.
