Improve documantation

[vanenshi]

Hello. Thank you for the awesome library. There are two issues with the documentation that, if resolved, would make it even easier to use your website.

1. Add a global search feature using https://www.algolia.com/, which is free for public repositories.
2. Enable support for AI tools indexing. It’s not possible to scan the document website using https://docs.cursor.com/context/@-symbols/@-docs#docs.
