• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y ((nang xa) OR (((nang ma) OR (tang ma)))) hoi. lieu va cham luc va hanh va cac tren*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y ((nang xa) or (((nang ma) OR (tang ma)))) hoi. lieu va cham luc va hanh va cac tren*".
