• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - hanh tran van hung ((((cong dan) OR (cong tan))) OR (cong san)) than cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - hanh tran van hung ((((cong dan) OR (cong tan))) or (cong san)) than cau*".
