• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y dang xa hoi. hieu ((ve cam) OR (ve cham)) cuc ((ban tinh) OR (ban hanh)) vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y dang xa hoi. hieu ((ve cam) or (ve cham)) cuc ((ban tinh) OR (ban hanh)) vi cua te".
• Adding a wildcard symbol may retrieve word variants: tu sach y dang xa hoi. hieu ((ve cam) or (ve cham)) cuc ((ban tinh) OR (ban hanh)) vi cua te*.
