• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc chieu) OR (ho chieu)) tinh - hanh sinh cua nhung cong van ((quan cua) OR (van ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) OR (ho chieu)) tinh - hanh sinh cua nhung cong van ((quan cua) or (van ban))~".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) OR (ho chieu)) tinh - hanh sinh cua nhung cong van ((quan cua) or (van ban))*.
