People always sell Sear, but myself, I'm a fan of presearch.com I have no affiliation with them whatsoever or financial interest. I have no interest in their crypto based business model. In fact I think their lack of google or bing style search result filtering is entirely due to lack of funding and/or prioritizing other things more important to success, not due to taking a stand on free speech or anything like this. And that's perhaps how it was in the early days of the internet, when maslow's hierarchy of corporate needs focused on trying to make the thing work versus public relations goodfeels and presenting only rightspeech.

Anyway, if I'm looking for some topic I believe google would be known to filter heavily, or something esoteric, I take a look at presearch to get a second opinion. I'd also love to see archive.org do something similar, archive.org has an amazing collection of data, poorly indexed and poorly searchable.
