• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (tu sach)) tu lang xa hoi. hieu ve cao duc ((va thanh) OR (va tinh)) gian cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) OR (tu sach)) tu lang xa hoi. hieu ve cao duc ((va thanh) or (va tinh)) gian cua te".
