• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (te sach)) ky nang xa hoi. thien van nhan luc va ((thanh dai) OR (thanh hai)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (te sach)) ky nang xa hoi. thien van nhan luc va ((thanh dai) OR (thanh hai)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (te sach)) ky nang xa hoi. thien van nhan luc va ((thanh dai) OR (thanh hai)) cua tre".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (te sach)) ky nang xa hoi. thien van nhan luc va ((thanh dai) OR (thanh hai)) cua tre*.
