Searching for words that match Python keywords won't return anything

This was first noticed here: https://github.com/astral-sh/ruff/issues/21869

It seems keywords are excluded. Searching for while, if, for, from, etc., using the search bar will only result in words or blobs that contains the text, but not the text itself.

Any of those keywords give no results on MKDocs own website as well. https://www.mkdocs.org/
