• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chu) OR (ho chieu)) tinh - anh tang cua trong cong van ((toan cau) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chu) or (ho chieu)) tinh - anh tang cua trong cong van ((toan cau) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: ((theo chu) or (ho chieu)) tinh - anh tang cua trong cong van ((toan cau) OR (toan tap))*.
