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