• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - canh ((tranh va) OR (trang va)) nang cong ((dan toan) OR (dan chan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - canh ((tranh va) OR (trang va)) nang cong ((dan toan) or (dan chan)) cau*".
