• If you are trying to use Boolean operators, they must be ALL CAPS: te cac ky nang xa hoi. hieu ((va cam) OR (((ve chat) OR (va chat)))) tuc va vanh dai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te cac ky nang xa hoi. hieu ((va cam) or (((ve chat) OR (va chat)))) tuc va vanh dai cua triet".
• Adding a wildcard symbol may retrieve word variants: te cac ky nang xa hoi. hieu ((va cam) or (((ve chat) OR (va chat)))) tuc va vanh dai cua triet*.
