• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sac) OR (te san)) ky nang xa hoi. hieu ve cham luc van hanh ((di cua) OR (dai cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sac) OR (te san)) ky nang xa hoi. hieu ve cham luc van hanh ((di cua) or (dai cua)) te".
• Adding a wildcard symbol may retrieve word variants: ((te sac) OR (te san)) ky nang xa hoi. hieu ve cham luc van hanh ((di cua) or (dai cua)) te*.
