• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (theo chieu)) xanh - hanh ((trang va) OR (tran van)) nhung huong anh luan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (theo chieu)) xanh - hanh ((trang va) OR (tran van)) nhung huong anh luan ban~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (theo chieu)) xanh - hanh ((trang va) OR (tran van)) nhung huong anh luan ban*.
