• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sach ty)) nang x hoi. thi van cau duc ((van hang) OR (van khang)) va chua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) or (sach ty)) nang x hoi. thi van cau duc ((van hang) OR (van khang)) va chua tre*".
