• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - canh manh cua ((((nhung cong) OR (nhung don))) OR (dung cong)) san pham cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - canh manh cua ((((nhung cong) OR (nhung don))) or (dung cong)) san pham cau~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - canh manh cua ((((nhung cong) OR (nhung don))) or (dung cong)) san pham cau*.
