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