• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu sang) OR (nhieu tang)) - hanh trung tam ((han nong) OR (phan cong)) san thanh lap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sang) or (nhieu tang)) - hanh trung tam ((han nong) OR (phan cong)) san thanh lap*".
