Flutterby™! : Tantivy

Simon Willison mentioned a Rust full-text search library called Tantivy.

Thinking more and more about that search engine that takes in OPML files and does a search of that RSS + some depth, and gives us each a personal search engine, with much better spam control. We're in a world where storage on a home server, and probably even a relatively cheap colo machine, can definitely hold the amount of knowledge we want to search, if we can figure out how to cull the Inkernets to the valuable stuff.

Maybe networks of blogs communicating via RSS can be that.
