tinysearch is a lightweight, fast, full-text search engine. It is designed for static websites.

tinysearch is written in Rust, and then compiled to WebAssembly to run in a browser.
It can be used together with static site generators such as Jekyll, Hugo, Zola, Cobalt, or Pelican.

tinysearch is a Rust/WASM port of the Python code from the article "Writing a full-text search engine using Bloom filters". It can be seen as an alternative to lunr.js and elasticlunr, which are too heavy for smaller websites and load a lot of JavaScript.

Under the hood it uses a Xor Filter — a datastructure for fast approximation of set membership that is smaller than bloom and cuckoo filters. Each blog post gets converted into a filter that will then be serialized to a binary blob using bincode. Please note that the underlying technologies are subject to change.

Only finds entire words, so not suitable for my usage on this site
