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