• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty xang xa hoi. hieu ((ve cham) OR (ve chat)) soc ban hanh vai ((dua tren) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty xang xa hoi. hieu ((ve cham) OR (ve chat)) soc ban hanh vai ((dua tren) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: su sach ty xang xa hoi. hieu ((ve cham) OR (ve chat)) soc ban hanh vai ((dua tren) or (cua te))*.
