Queries can search over text in the tagged languages by specifying which language to search and which languages to return. The syntax
@lang1:...:langN 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.
