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