Sorting by "Critic rating" and "Rating" seem to do nothing for me.
Searching for a movie by the orginal title won't work for some movies. For example, when I search for "lord of the rings" I get 0 results (see second picture). But if I search for "Sagan om de två tornen" which it's called in Sweden (I have library language set to swedish, see first picture) it finds the movie. I have checked, the Orginal title is set to "The Lord of the Rings: The Two Towers" However, If I manually set the orginal title to some random rubberish and search for it in global seach it finds it. This issue is present for example all of my three lord of the rings movies.
