## Checklist

- [x] I searched for existing GitHub issues
- [x] I updated all Cordova tooling to most recent version
- [x] I included all the necessary information above

Start at https://cordova.apache.org/ and reproduce the global search failure by submitting “android”; inspect the website search entry point and how it builds the resulting URL. Done means the search returns relevant results instead of only adding a “?” to the URL.
