• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - thanh ((trung tuan) OR (truong cao)) thong thuong dan ((chan cap) OR (cao cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - thanh ((trung tuan) or (truong cao)) thong thuong dan ((chan cap) OR (cao cap))~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - thanh ((trung tuan) or (truong cao)) thong thuong dan ((chan cap) OR (cao cap))*.
