• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky ((sang lap) or (tang ma)) hai. hieu ve cam ((xuc va) OR (luc va)) dao dai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((sang lap) OR (tang ma)) hai. hieu ve cam ((xuc va) OR (luc va)) dao dai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((sang lap) or (tang ma)) hai. hieu ve cam ((xuc va) OR (luc va)) dao dai cua te".
• Adding a wildcard symbol may retrieve word variants: tu sac ky ((sang lap) or (tang ma)) hai. hieu ve cam ((xuc va) OR (luc va)) dao dai cua te*.
