Dgraph DQL Tour
Dgraph supports string text and queries as UTF-8.
String valued predicates can be annotated with a language tag.

Queries can search over text in the tagged languages by specifying which
language to search and which languages to return. The syntax
specifies the preference order for returned languages with the following rules:
- at most one result will be returned
- if results exists in the preferred languages, the left most (in the preference list) of these is returned
- if no result exists in the preferred languages no result is returned unless
the preference list is terminated with
., in which case the value without a specified language is returned, or if there is no value without language, a value in “some” language is returned.
