• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang xa hoi. hieu viec ((lam luc) OR (lam duoc)) va hanh ((di cua) OR (dai cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang xa hoi. hieu viec ((lam luc) OR (lam duoc)) va hanh ((di cua) or (dai cua)) te".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang xa hoi. hieu viec ((lam luc) OR (lam duoc)) va hanh ((di cua) or (dai cua)) te*.
