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