• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - hanh tang chua hang cong ((dan than) OR (((manh toan) OR (thanh toan)))) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh tang chua hang cong ((dan than) or (((manh toan) OR (thanh toan)))) cao~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh tang chua hang cong ((dan than) or (((manh toan) OR (thanh toan)))) cao*.
