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