• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu xanh - hang ban cua ((hang cong) OR (bang cong)) thanh ((tuan tai) OR (quan tai))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - hang ban cua ((hang cong) OR (bang cong)) thanh ((tuan tai) or (quan tai))~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - hang ban cua ((hang cong) OR (bang cong)) thanh ((tuan tai) or (quan tai))*.
