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