• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((nang xa) OR (nang ma)) hoi. lieu va cac tu ((va hanh) OR (dia danh)) diem cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((nang xa) OR (nang ma)) hoi. lieu va cac tu ((va hanh) or (dia danh)) diem cau tren".
• Adding a wildcard symbol may retrieve word variants: te sach ty ((nang xa) OR (nang ma)) hoi. lieu va cac tu ((va hanh) or (dia danh)) diem cau tren*.
