There is problem that appears when you are trying to relate works with very short titles.
The choices that appear are all longer titles, but not the correct “one word” title, e.g.
I wanted to link the German translation “Nacht” to the original story “Night”, but I couldn’t because “Night” was not displayed. (I wonder why “Nicholas Nickleby” seems to be a better fit than “Night” for the search engine
Fortunately it worked the other way round, but for the future we’ll need a solution for this problem.
