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