It's the first solo project I've done in many years and I'm having a great time learning. I've also been able to get some great recommendations for myself and it's fun to use!
However, I gave it "Jane Eyre" (a mid-19th century novel by Charlotte Bronte; it's a classic) with the expectation that it will return "Wuthering Heights" – another a classic novel written in mid-19th century by Emily Bronte (yes the authors are related) – among other things. People who like Jane Eyre tend to like Wuthering Heights, and vice versa.
But everything it returned were new works – published in the last 20 years – of stories that are set in the 19th century.
The only filters applied were: "Preferred: Gothic romance novel, Victorian literature, Highly influential classic literature, Early 19th-century England ".
So, something seems amiss for now. Nevertheless, it's a very cool idea.
(Edited to fix my grammar; English is not my first language, so pardon me for any mistakes.)
This is happening because I intentionally added a strong bias for more recent books. I thought that's what most people would be looking for - at least for fiction - and I also assumed there were other good ways to discover older books (lists, collections etc).
You're absolutely right though, it should give you some Victorian lit given your preferences! I'll work on addressing this.
