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