Translations & Search
You can have several languages in your service. Which language is shown to your customers is based on the language used on the customer's device.
If the language on the customer's device matches any of the available translations it will use that language file.
If the language on the customer's device doesn't match any of the available translations it will use the default language.
Search
The search is also defined by the language used on the customer's device. When a user searches for content in your service, the search query will look for terms in the matching translation file and in the default file.
