Add a search bar

[CreepySkeleton]

It looks like you're using mdbook to render the book. mdbok has the built-in search bar that looks like this

Could you please add this ability to serde.rs?

I just forked and rebuilt the md files with material mkdocs. Check this out.

There're still some issues with code blocks and anchors I will try to fix it, but at least you got a searchable serde doc now!
