• I have read the Contributing Guidelines on issues.

Prerequisites

• I'm using the latest version of Docusaurus.
• I have tried the npm run clear or yarn clear command.
• I have tried rm -rf node_modules yarn.lock package-lock.json and re-installing packages.
• I have tried creating a repro with https://new.docusaurus.io.
• I have read the console error message carefully (if applicable).

Description

Hello there!

I'm trying to add a message at the bottom of Algolia search results that prompts the user to open a GitHub issue if no results are found. The Docusaurus documentation pointed me to the Algolia DocSearch documentation which references a getMissingResultsUrl option. That option isn't available on the algolia config type but I tried anyway as I thought it might still work.

Unfortunately, it doesn't. So I'm guessing the search component used inside Docusaurus doesn't take this option into account.

Reproducible demo

https://stackblitz.com/edit/github-kv4zyn?file=docusaurus.config.ts

Steps to reproduce

1. Update algolia.appId and algolia.apiKey with valid values
2. Use the search functionality to find something that doesn't exist (I use thisissomethingthatdoesntexist)
3. See that a "missing results" blurb is not present (as seen here)

Expected behavior

The "missing results" blurb should be visible and editable.

Actual behavior

There is no "missing results" sentence, nor does one appear if the getMissingResultsUrl option is set.

Your environment

No response

Self-service

• I'd be willing to fix this bug myself.
