• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) OR (vu sach)) ty xang xa hoi. thien van cac xuc van ((dinh vai) or (dinh van)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) ty xang xa hoi. thien van cac xuc van ((dinh vai) OR (dinh van)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) ty xang xa hoi. thien van cac xuc van ((dinh vai) or (dinh van)) cua te".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (vu sach)) ty xang xa hoi. thien van cac xuc van ((dinh vai) or (dinh van)) cua te*.
