Also, have you thought about partnering with commoncrawl.org? I could see that relationship benefiting both sides: they get fresher indices, you get access to the historical web snaps
The problem is that if you were to build a new search engine from the ground up it will take millions in infrastructure, and a lot of time for you to test one idea. And there are multiple attack vectors to Google's business model (privacy, subscription model, modality, etc.) however you might get the change of testing one of them, and if that fails, starting again is super expensive so you might not be able to get funds to do it.
My approach then became to build something that others can build on top of.
I'm currently using common crawl but my main problem is that I need to build a small toy to test it and even processing common crawl is crazy expensive. Just a single snap are 150 Tb, so this needs to be process on metal, or you're gonna pay a hefty AWS bill.
For that specific search I would start at Wikipedia, but for more general "data search" I lean towards Wolfram Alpha, which has some usability issues, but interesting maths engine for queries. https://www.wolframalpha.com/input?i=Barack+Obama+vs+Donald+...
I’ve been dreaming of an open web index and social graph for more than a decade.
Any company having the data + the algorithm + the presentation layer is way too much power. We can and should split that problem into its separate domains.
I hope you succeed, keep us posted.
is what I saw as the primary difference. Whether that's going to pan out in reality as well as it does in HN comments is "the devil's in the details" though
