This is really really cool. I had earlier wanted to entirely run my searches on it and though that seems possible, I feel like it would be sadly a little bit more waste of time in terms of searches but still I'll maybe try to run some of my searches against this too and give me thoughts on this after doing something like this if I could, like, it is a big hit or miss but it will almost land you to the right spot, like not exactly.

For example, I searched lemmy hoping to find the fediverse and it gave me their liberapay page though.

Please, actually follow up on that common crawl promise and maybe even archive.org or other websites too and I hope that people are spending billions in this AI industry, I just hope that you can whether even through funding or just community crowdwork, actually succeed in creating such an alternative. People are honestly fed up with the current search engine almost monopoly.

Wasn't Ecosia trying to roll out their own search engine, They should definitely take your help or have you in their team..

I just want a decentralized search engine man, I understand that you want to make it sustaianable and that's why you haven't open sourced but please, there is honestly so much money going into potholes doing nothing but make our society worse and this project almost works good enough and has insane potential...

Please open source it and lets hope that the community tries to figure out a way around some ways of monetization/crowd funding to actually make it sustainable

But still, I haven't read the blog post in its entirety since I was so excited that I just started using the search engine.., But I feel like the article feels super indepth and that this idea can definitely help others to create their own proof of concepts or actually create some open source search engine that's decent once and for all.

Not going to lie, But this feels like a little magic and I am all for it. I have never been this excited the more I think about it of such projects in actual months!

I know open source is tough and I come from a third country but this is actually so cool that I will donate ya as much as I can / have for my own right now. Not much around 50$ but this is coming from a guy who has not spent a single penny online and wanting to donate to ya, please I beg ya to open source and use that common crawl, but I just wish you all the best wishes in your life and career man.

At the end, the author thinks about adding Common Crawl data. Our ranking information, generated from our web graph, would probably be a big help in picking which pages to crawl.

I love seeing the worked out example at scale -- I'm surprised at how cost effective the vector database was.

I been doing a smaller version of the same idea for just domain of job listings. Initially I looked at HNSW but couldn't reason on how to scale it with predictable compute time cost. I ended up using IVF because I am a bit memory starved. I will have to take at look at coreNN.

This is so cool. A question on the service mesh - is building your own typically the best way to do things?

I'm new to networking..

This then begs the question for me, without an LLM what is the approach to build a search engine? Google search used to be razor sharp, then it degraded in the late 2000s and early 2010s and now its meh. They filter out so much content for a billion different reasons and the results are just not what they used to be. I've found better results from some LLMs like Grok (surprisingly) but I can't seem to understand why what was once a razor exact search engine like Google, it cannot find verbatim or near verbatim quotes of content I remember seeing on the internet.

My understanding was that every few months Google was forced to adjust their algorithms because the search results would get flooded by people using black hat SEO techniques. At least that's the excuse I heard for why it got so much worse over time.

Not sure if that's related to it ignoring quotes and operators though. I'd imagine that to be a cost saving measure (and very rarely used, considering it keeps accusing me of being a robot when I do...)

From what I understand, that good old Google from the 2000s was built entirely without any kind of machine learning. Just a keyword index and PageRank. Everything they added since then seems to have made it worse (though it did also degrade "organically" from the SEO spam).

This is my take as well. When websites were few, directories were awesome. When websites multiplied, Google was awesome. When websites became SEO trash, social networks were awesome. When social networks are become trash, I'm hoping the Fediverse becomes the next awesome.

I don't see AI in any form becoming the next awesome.

I wish all the best wishes to fediverse too. I'd like to take this one step too that communities have gone a similar transition too from forums to mostly now discord and I wish them to move to something like matrix which is federated (yes I know it has issues, but trust me sacrifices must be made)

What are your thoughts on things like bluesky/nostr and (matrix) too.

Bluesky does seem centralized in its current stage but its idea of (pds?) makes it fundamentally hack proof in the sense that if you are on a server which gets hacked, then your account is still safe or atleast that's the plan, not sure about its current implementation.

I also agree with AI not being the next awesome. Maybe for coding sure, but not in general yeah. But even in coding man, I feel like its good enough and its hard to catch more progress from now on and its just not worth it but honestly that's just me.

The majority of the public internet shifted to "SEO optimized" garbage while the real user-generated content shifted to walled gardens like Instagram, Facebook, and Reddit (somewhat open). More recently, even use generated content is poisoned by wannabe influencers shilling some snake oil or scam.

That begs the question, if you can recreate their engine from the 2000s with high quality search results, would investors even fund you? Lol

> if you can recreate their engine from the 2000s

Seriously, how? Iam pretty sure you have to have a very different approach than google had in its best times. The web is a very different place now

When I encounter the "cannot find verbatim quote I remember" problem and then later find what I was looking for in some other way, I usually discover that I misremembered and the actual quote was different. I do prefer getting zero results in that case, though.

I see you’re also having trouble coping with this. Fact is, “that” internet is simply gone.

Nah, its a series of tubes, just gotta get the right tubes together.

I wish there was an old fashioned n-gram + page rank search engine for those of us who don't mind the issues the older Google had. I've thought about making my own a few times.

Very nice project. Do you have plans to commercialize it next?
