Frustration with Searching for Lessons
I was trying to find the lesson on Chemistry but the search produced no results. I knew the lesson number (1011), but still no results.
I seem to be able to specify a search for a lesson number like 0894 which successfully returns the lesson on 孔子，but numbers above 999 don't seem to work.
Frustrated, after much trying, I searched for 'crap' which gave me the intermediate lesson speeding! I searched for 'rubbish' which gave me a lesson regional accents!
