• If you are trying to use Boolean operators, they must be ALL CAPS: te sach nay lang ha hoi. hieu ve ((cau luc) OR (cau truc)) va nhanh hai ((cua tu) OR (cua cu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach nay lang ha hoi. hieu ve ((cau luc) or (cau truc)) va nhanh hai ((cua tu) OR (cua cu))".
