• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (lieu tinh)) - anh ((nang van) OR (lang van)) dung cong san thanh cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (lieu tinh)) - anh ((nang van) OR (lang van)) dung cong san thanh cao*".
