• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ly) OR (sach ty)) nang ma hoi. hieu qua ca cuc ban hanh ((day cua) OR (dan cua)) tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ly) OR (sach ty)) nang ma hoi. hieu qua ca cuc ban hanh ((day cua) or (dan cua)) tu".
