• If you are trying to use Boolean operators, they must be ALL CAPS: te sach nganh ((((((cong khi) OR (cong hai))) OR (co khi))) OR (((hong ha) OR (long ha)))) đong luc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach nganh ((((((cong khi) or (cong hai))) or (co khi))) or (((hong ha) OR (long ha)))) đong luc".
