• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ((ky dang) OR (ky danh)) xa hoi. hieu vu cham cuu ban anh ve cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (te sach)) ((ky dang) OR (ky danh)) xa hoi. hieu vu cham cuu ban anh ve cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (te sach)) ((ky dang) OR (ky danh)) xa hoi. hieu vu cham cuu ban anh ve cua tre*.
