• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu sang) OR (((chiet tach) OR (chieu sach)))) - anh truong cao chung cong van tuan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu sang) or (((chiet tach) OR (chieu sach)))) - anh truong cao chung cong van tuan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu sang) or (((chiet tach) OR (chieu sach)))) - anh truong cao chung cong van tuan cau*.
