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