Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

I want to dive into how to make search engines
Not finished, but the Selenium based crawler works pretty well to combat most blocks: https://github.com/kordless/grub-2.0
For IP blocks, try this: https://github.com/kordless/mitta-screenshot

Ask HN: Decent, open source search engine?
I started https://mitta.us as this, but am pivoting to prompt management for GPT-3. I've Open Sourced the code for the crawler here: https://github.com/kordless/grub-2.0. The entire system uses Google Vision for extracting text. I dislike fiddling with the DOM...
If you are interested in using Solr for this, I can provide instructions to you. I'm kordless at the gmails ... com.

How to Scrape and Extract Hyperlink Networks with BeautifulSoup and NetworkX
Depending on the use case you might try imaging the page, then send the image to an ML model for full text before indexing. If you need links extracted, Selenium also supports parsing the assembled DOM: https://github.com/kordless/grub-2.0/tree/main/aperture

Mastering Web Scraping in Python: Crawling from Scratch
I’ve found imaging the page and doing OCR on the image is quite good for text extraction. Many pages on the Internet render with JavaScript, which means BS may not see the text in the DOM.
Here is the code to do some of that: https://github.com/kordless/grub-2.0

I want to dive into how to make search engines
I would try to grasp the 'random surfer' idea, that is modeled by a Markov Chain. A nice free book is Markov Chain for Programmers [1]. A discrete time Markov Chain boils down to a conditional probability that boils down to a matrix, and a steady distribution boils down to an eigenvalue 1 eigenvector of it, which determines PageRank. Then one can jump to 'The $25,000,000,000 Eigenvector: The Linear Algebra behind Google'.
