• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - hanh trang cua ((hang nguong) OR (hang thuong)) dan ((toan cao) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - hanh trang cua ((hang nguong) OR (hang thuong)) dan ((toan cao) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - hanh trang cua ((hang nguong) OR (hang thuong)) dan ((toan cao) or (toan ban))*.
