• If you are trying to use Boolean operators, they must be ALL CAPS: su sach tu nang xa hoi. thien van hanh thuoc ban thanh ((((ve cua) OR (ve cum))) OR (de cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach tu nang xa hoi. thien van hanh thuoc ban thanh ((((ve cua) OR (ve cum))) or (de cua)) tre".
