• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - canh ((((trinh vat) OR (trinh han))) OR (trinh luat)) dung cong san phan tu.

• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - canh ((((trinh vat) OR (trinh han))) or (trinh luat)) dung cong san phan tu*.
