Search bug when the search index contains HTML code for a redirect (HTML book)

[maelle]

Bug description

@jonthegeek noticed that when searching for "ht" in https://devdevguide.netlify.app/ he was redirected to a non-existing page immediately.

I was able to reproduce the bug with a minimal example https://github.com/maelle/search-bug

In https://github.com/maelle/search-bug/blob/main/summary.qmd I added the necessary Markdown including html code for a redirect (which is something we need to explain to readers of the original book). That code is present in the search index. If you search for "ht" in https://maelle.github.io/search-bug/ you'll get redirected to https://docs.ropensci.org/%3Cpkgname%3E/

I'm guessing it has something to do with the code not being escaped somehow? Yes, that's a very vague guess. 😅 And a potentially very niche problem.
