• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang xa hoi. hieu ((van ban) OR (van hai)) ((truc va) OR (trung va)) danh di cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang xa hoi. hieu ((van ban) or (van hai)) ((truc va) OR (trung va)) danh di cua te".
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang xa hoi. hieu ((van ban) or (van hai)) ((truc va) OR (trung va)) danh di cua te*.
