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