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