• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang ma hoi. hieu ((ve cham) OR (ve chat)) ((tuc va) OR (thuc va)) hinh dinh cho tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang ma hoi. hieu ((ve cham) or (ve chat)) ((tuc va) OR (thuc va)) hinh dinh cho tre".
