• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sach y)) ((mang may) OR (lang van)) hoi. hieu va cham soc van thanh vi cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sach y)) ((mang may) or (lang van)) hoi. hieu va cham soc van thanh vi cuu tre*".
