• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang mai khoi. ((lieu ha) OR (lieu nha)) nam ((thuoc xa) OR (thuoc la)) hanh tai cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang mai khoi. ((lieu ha) OR (lieu nha)) nam ((thuoc xa) or (thuoc la)) hanh tai cau tren".
