Improved search engine

[Greenheart]

For now, the initial search is a good start. But it could be improved in the future.

This would require a server component, but might be worth it since it could save us time to focus on other things.

However, there might be a better client side search library out there that could help. Perhaps a library using WebAssembly modules to improve performance.
