• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sach ty)) nang cau hoi. hieu ve cam luc va thanh ((tai cua) OR (thai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) or (sach ty)) nang cau hoi. hieu ve cam luc va thanh ((tai cua) OR (thai cua)) tre".
