• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) xanh - manh trung cap ((khong can) OR (khong van)) ban thanh chu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (hoc thieu)) xanh - manh trung cap ((khong can) OR (khong van)) ban thanh chu".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc thieu)) xanh - manh trung cap ((khong can) OR (khong van)) ban thanh chu*.
