How Does Progscrape Rank Pages?

[ChiefMateStarbuck]

Hello,

I'm attempting to build a similar website to progscrape based on Travel. I'm attempting to understand the ranking engine in progscrape. There is the scrorer.rs file but I cant understand it. Would you be able to explain it? Is there any articles or books you can share on the subject? Thank you in advance and thank you for making progscrape open source.
