In query results, features with highway=busway and emergency=yes are listed only as "yes" in query results.

New entry for highway=busway to be added here: https://github.com/openstreetmap/openstreetmap-website/blob/master/config/locales/en.yml#L920

According to https://github.com/openstreetmap/openstreetmap-website/blob/master/CONTRIBUTING.md#nominatim-prefixes, "I18n keys under the geocoder.search_osm_nominatim" are managed by Nominatim maintainers.

I'm not exactly clear how this was done in the past. Maybe @lonvia can help here.

Feel free to add new entries. And feel free to make a PR to get of this section in CONTRIBUTING.md.

Not all projects work with assignments. Especially to new contributors. This can result in cookie licking.
Go ahead, get familiar to the code base and work on this if you like.
If you solve this. Hurray!
