• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((tay dang) OR (((tay dong) OR (day dong)))) van hoi. lieu va coc luc da nang tai cuc te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((tay dang) or (((tay dong) OR (day dong)))) van hoi. lieu va coc luc da nang tai cuc te*".
