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