"a given language + the default language if there’s no translation" is
not enough if we go this way, it should be a given language, then its
parents until you hit default language (for example "fr_FR", "fr",
"").

Note: we have a "locales" field in Solr for each document indicating
for which of the supported languages it should be matched (for
example. a document in default language and no translation will have
all the supported locales listed in this field so that if you filter
on any of those in the request you will find this document).
