If your content is mostly static, you might want to consider pre-building an index and shipping it as a whole. You could look into something like

* https://stork-search.net/ (Rust/WASM)

* tinysearch: https://github.com/tinysearch/tinysearch (Rust/WASM)

* https://lunrjs.com/ (JS, simple, stable)

* http://elasticlunr.com/ - based on the former, slightly more sophisticated tuning options
