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