Algolia Contextual Search Generates Incorrect FaceFilters

[slorber]

If that helps anyone stumbling on this issue, I posted this answer in a few Algolia issues, hope it helps.

No search result?

For anyone passing by, if you don't get any Algolia search results:

• make sure that your Algolia index has the fields in the screenshot below
• If you don't see these fields, then you have an index config problem
• You should check your crawler config, make sure it matches the recommended one, and then delete/recreate your index based on the newly updated/fixed crawler config (Algolia team recommendation)

We can close this ticket. I figured out the issue.
Check your index and make sure language is an exposed facet.

I'm not sure if the default Algolia crawler config is what's causing the issue but lang is not gonna help you. You need to make sure the face language is an attribute available on you index.

{
      attributesForFaceting: [
        "type",
        "lang",
        "language",
        "version",
        "type",
        "docusaurus_tag",
      ]
}

I hope this saves other some time 😅

Yes, you need to make sure your index match our official recommendations, otherwise it's your responsibility to make things work

The recommended config contains that "language" facetting field

@slorber would you be open to a PR that adds this tiny bit of information to the https://docusaurus.io/docs/search#contextual-search page? It could be a tiny lil info box and that also links to the issue #6693

Happy to author it.

@karl-cardenas-coding thanks for your proposal, but it was already on my todo list to add this index troubleshooting section so I just did it (#10056).

We get many support requests about this over time so it's important to explain this thing properly so I preferred to do it myself.

No worries 😊 @slorber and thank you for adding the updates. That's gonna help a lot for future users.
