• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach tu)) hang ha hoi. hieu van lam xuc ((va danh) OR (va dan)) vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) or (sach tu)) hang ha hoi. hieu van lam xuc ((va danh) OR (va dan)) vai cua tre".
