• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - hanh mang cua nhung ((cong tan) OR (cong thanh)) ((toan ban) OR (ran cau))~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - hanh mang cua nhung ((cong tan) or (cong thanh)) ((toan ban) or (ran cau))*.
