• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (ho chieu)) sang - hanh tranh ((cua hang) OR (cua nhung)) nong ban nang cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (ho chieu)) sang - hanh tranh ((cua hang) OR (cua nhung)) nong ban nang cao~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (ho chieu)) sang - hanh tranh ((cua hang) OR (cua nhung)) nong ban nang cao*.
