• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (vu sach)) ky nang xa hoi. ((hieu viec) OR (hieu ve)) cac xuc cam doan vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) ky nang xa hoi. ((hieu viec) OR (hieu ve)) cac xuc cam doan vi cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (vu sach)) ky nang xa hoi. ((hieu viec) OR (hieu ve)) cac xuc cam doan vi cuu tre".
