• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu san) OR (thuy san)) ky nang ma hoi. ((hieu vien) OR (hieu viec)) cac luc va danh co cua su~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu san) OR (thuy san)) ky nang ma hoi. ((hieu vien) or (hieu viec)) cac luc va danh co cua su~".
• Adding a wildcard symbol may retrieve word variants: ((thu san) OR (thuy san)) ky nang ma hoi. ((hieu vien) or (hieu viec)) cac luc va danh co cua su*.
