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