• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (thu sach)) ky nang xa hoi. thieu nien dai ((xuc va) OR (luc va)) khanh vinh cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (thu sach)) ky nang xa hoi. thieu nien dai ((xuc va) OR (luc va)) khanh vinh cuu tre*".
