I'm Marcus, founder of Didyougogo and author of the software behind it. For the past ten years I've been trying to improve my programming and math skills to get to a level where I could write a proper web search engine for the written word using absolute cutting-edge IR methods. The final result is something I have not seen or read about: a language represented as a 65K wide vector-space, serialized into a binary tre…

I'm glad I could make you curious about this. I will gladly expand on the documentation around the language model and querying as soon as I can. In broad terms: its a 16-bit vector space in which you can encode anything you like. I have chosen to encode phrases and words as bags-of-characters. This separates terms from each other enough that they can be searched for reliably (in almost all cases). Terms that share a…

Could the bags-of-characters approach cause issues with anagrams having the same vector?

It would be surprising (to me) to get the same results for e.g. "strange" and "garnets".

Earlier quoted context omitted.

The catch is: this is 0.1 alpha software. I need a small team and some server capacity to get rolling. I need people to submit URLs. And a few hundred queries per second. That would scare the living shit out of big league search engines and might wake up some investor wanting to throw money at this.

In addition to users submitting articles, is there a reason this doesn't have a spider of its own based off something like the Google zeitgeist to seed some topics? This project looks neat, I think first experiences with it would be much more improved if you could seed it with some content. Maybe this could run my search with other search engines to compare and gain insights.

"is there a reason this doesn't have a spider"

Yes, server capacity. Once I have a better hosting situation I'll start crawling.

Thank you, I've tried to be neat this time around.

With regards to full-text search, the didyougogo search engine should be able to replace elasticsearch (which is laughable relevance-wise in my eyes) or solr, once the alpha-bugs are gone.

Name makes it sound like it's related to DDG. Definetely need a better one.

I thought it was a nice homage to DuckDuckGo. What it really means is "Did you submit both a query and a URL?"

I think you have to provide a URL and some keyword.

The index is super tiny. A search for "the" got 112 results. Seems like a quick way to explore the entire index. Also it indexes pages twice if you submit them twice, so that needs to be fixed. But for some crazy reason, I kinda like this. It feels like the 90s internet. The links included so far have that same random mix of lots of nerdy links, homepages & personal blogs, a few religious sites, and the occasional bi…

My reaction was similar. The first search I entered was "Current weather in [my hometown]." Nothing close. So I generalized a bit to "National Weather Service." The first result was a VPN company website. Then I realized you can (should) enter search terms AND a URL. After submitting weather.gov's URL, a search for "National Weather Service" instantly starting returning weather.gov as the first result. As the parent commenter said, it very much has the feel of the 90's web that I remember so fondly (and perhaps inaccurately). I'll definitely continue to keep an eye on this project.
