Search Functionality is not fetching any results on 404 Page

[Codex-Bugmenot]

Describe the bug

The Search Functionality (ctrl + K) fetches results based on query typed in the search field but in a 404 page the results are shown as "No Results Found" for every query

To reproduce

1. Go to any 404 page , i used "https://ethereum.org/en/1"
2. Click on Search Bar or hold (ctrl + K)
3. Search for any known search term in the website
4. Observe that is fetches no results no matter the query

Expected behavior

The Search Functionality should Fetch Results in a 404 i.e in case some one really ends up in a 404 page they should be able to find their way back through search

Would like to add that the language change doesn't work either, which leads me to suspect that the DEFAULT language messes up the logic discussed in this issue, as well as in issues #12471 and #12292.

Yeah.. I agree @tomasgrusz... think we're starting to see the edge cases from that default locale decision.

The search component utilizes Algolia, which does include a "facet" option that breaks up the index according to the lang attribute assigned to the html element... in the case of the 404 page, this is being set to default instead of en. We're then querying for a part of our index with lang="default", which doesn't exist.

I'll assign myself for now, but also cc: @pettinarip to keep you in the loop here. I'll take a look at Algolia and see if there is anything we can do on that end to try and use the en index as the default.
