• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((tu nang) OR (tru nang)) xa hoi. hieu ve ((cac xuc) OR (cap nuoc)) van hanh vi cua su.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((tu nang) OR (tru nang)) xa hoi. hieu ve ((cac xuc) or (cap nuoc)) van hanh vi cua su".
• Adding a wildcard symbol may retrieve word variants: te sach ((tu nang) OR (tru nang)) xa hoi. hieu ve ((cac xuc) or (cap nuoc)) van hanh vi cua su*.
