• If you are trying to use Boolean operators, they must be ALL CAPS: doc hieu manh - canh tranh cua ((((dong cong) OR (cong cong))) OR (dang cong)) dang hanh cat*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc hieu manh - canh tranh cua ((((dong cong) OR (cong cong))) or (dang cong)) dang hanh cat*".
