lng

BCP47 Language Tag specifying the language of the displayName entry. Search does NOT consider lng while scoring the results.
This attribute is used for display purpose in map and for providing the place title and subtitle in the correct language that was requested (or default
language for that place). For example while looking for a place called even internationally as "Shell" it matters to choose a right language as for
Slovak language the subtitle would be "Bratislavská ulica" while for English it would be "Bratislava street" and for Hungarian "Pozsonyi utca".
When choosing a default language (while not having a match with the requested language), always the first indexed language is used both for search
purpose and for map display purpose.
