• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach tu)) xang xa hoi. hieu van chat xuc ((ban hanh) OR (va tinh)) vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) OR (sach tu)) xang xa hoi. hieu van chat xuc ((ban hanh) or (va tinh)) vai cua tre*".
