• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach ty mang mai hoi. hieu van ((cham lo) OR (cam lo)) va ((hanh vai) OR (hanh vi)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach ty mang mai hoi. hieu van ((cham lo) or (cam lo)) va ((hanh vai) OR (hanh vi)) cua te".
