Setting my Region for News to "Luxembourg (LU)" will return only French results, ignoring all results written in Luxembourgish (e.g. from www.rtl.lu) or German (wort.lu).
E.g. there was a recent story about an EMT getting suspended. Searching for it in Luxembourgish news with the Luxembourgish word for it ("Samusdokter") yielded zero results - obviously because it's not a French word, which the Luxembourgish news search filters for.
I'd expect a blend of all official languages (French, German, Luxembourgish) concerning Luxembourg by default (and possibly, but feature request: some configurability / prioritization of search result languages).
Resulting in a non-empty page when searching for Luxembourgish or German words on the news page for the Luxembourg Region.
