hoc thieu » toc thieu, hoc hien

• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - thanh tran van hung ((cong dan) OR (huong dan)) ((than cap) OR (khan cap))~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - thanh tran van hung ((cong dan) or (huong dan)) ((than cap) or (khan cap))*.
