I just discovered https://hister.org/ (I think from a link here on hacker news) ... it solves the full text history search really really well.

  - Local go server to index everything into sqlite or postgres
  - browser extension to send the DOM for indexing. 
    - This happens after each page is finished rendering, so client side rendering doesn't break, and it doesn't require fetching the url a second time on the back-end.
  - Filter rules to control what gets indexed (basic url regex patterns, nothing too fancy)
  - Text-based query interface for terminal dwellers like me.
  - Local file indexing that actually works well so that you can search your history and your documents in one place.
  - Custom extractors for understanding specific sites and file formats.

It's really great, just about perfect for my needs.
