• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu tinh - hanh trinh lam trong cong ((((dan phan) OR (dan chan))) OR (doan phan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu tinh - hanh trinh lam trong cong ((((dan phan) OR (dan chan))) or (doan phan)) cau*".
