The search works great. I'm using MkDocs with Material as my personal handbook because of the simplicity -- for example, I usually remember great articles in conversations but always forget their location. Since I started writing my newsletter https://opsindev.news/ including an MkDocs web archive, I can share interesting URLs way faster :) Or let folks discover it by themselves, using the search.
Material for MkDocs also has an insiders build, accessible through sponsorship. https://squidfunk.github.io/mkdocs-material/insiders/ These features add more value to MkDocs -- I initially joined to get GDPR-compliant cookie banners and stayed to support a great project.
