• If you are trying to use Boolean operators, they must be ALL CAPS: ((doi chieu) OR (ho chieu)) sach - hanh mang cua truong ((cong tap) OR (cong tan)) dan ca~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) OR (ho chieu)) sach - hanh mang cua truong ((cong tap) or (cong tan)) dan ca~".
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) OR (ho chieu)) sach - hanh mang cua truong ((cong tap) or (cong tan)) dan ca*.
