Hello,
the search terms must be part of the title for the search to work. That's why "Brin de mus" works but not "brin musette".
jpg, I'm interested in what you wrote. How did you find 19s and 40s?
You mean the time to scroll to find the score?
I have set up an auto-completion system on the score search field by title (takes a few seconds to find) while waiting for the rework of the deeper search to be done.
