Search for "Pledge" does not find the Code of Conduct

Problem: I was not able to use the search box and hit the word "Pledge", which is in the Code of Conduct document.

This `config.rb` stanza

`search.resources = ["index.html", "guides/", "#{config[:current_version]}/", "changelog.html", "compatibility.html", "conduct.html", "contributors.html"]`

is perhaps not good for "vendored documents"?
