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