The problem for the store here (using the Camera example) is that no translations have been added to the metadata. The phone will send an `Accept-Language` header with the request to indicate the language in use on the device, and we will search using the terms entered by the user against that language and the default, untranslated metadata, scoring packages that match the translated fields more highly.

As an example:

```
$ curl -s 'https://search.apps.ubuntu.com/api/v1/search?q=otp%20transit&fields=title,description,keywords,translations' | jq .

The solution that will work today is for the uploader to add the translations. A possible future improvement would be to try to extract the translations from, say, a `.desktop` file in the package, but that's problematic for various reasons:

 * What about packages that only ship scopes (no `.desktop` file)?
 * What about packages that ship several apps (several `.desktop` files)?
 * What about snap packages that are targeting IoT/Ubuntu Core (zero or more `.desktop` files, but not referenced in the manifest)?
