• If you are trying to use Boolean operators, they must be ALL CAPS: vu ban ky ((nang xa) OR (lang xa)) hoi. ((hieu viec) OR (nhieu viec)) cac luc va hanh vai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ban ky ((nang xa) or (lang xa)) hoi. ((hieu viec) OR (nhieu viec)) cac luc va hanh vai cua te*".
