• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ky dang) OR (ky nang)) xa hoi. hieu ve cham xuc va den vai ((cuu tre) OR (cau tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ky dang) or (ky nang)) xa hoi. hieu ve cham xuc va den vai ((cuu tre) OR (cau tren))".
• Adding a wildcard symbol may retrieve word variants: te sach ((ky dang) or (ky nang)) xa hoi. hieu ve cham xuc va den vai ((cuu tre) OR (cau tren))*.
