• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - thanh truong ((cua thong) OR (cua tong)) ((cong luong) OR (nang luong)) thanh cha~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh truong ((cua thong) or (cua tong)) ((cong luong) OR (nang luong)) thanh cha~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh truong ((cua thong) or (cua tong)) ((cong luong) OR (nang luong)) thanh cha*.
