• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((nganh cong) OR (thanh cong)) nghe thuong tinh ((va truyen) OR (di truyen)) thong.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((nganh cong) or (thanh cong)) nghe thuong tinh ((va truyen) OR (di truyen)) thong".
• Adding a wildcard symbol may retrieve word variants: tu sach ((nganh cong) or (thanh cong)) nghe thuong tinh ((va truyen) OR (di truyen)) thong*.
