• Performing a fuzzy search may retrieve terms with similar spellings: ((su sac) OR (su cac)) ky tang ma hoi. hieu ((ve cam) or (ve cham)) duc ban thanh dai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su cac)) ky tang ma hoi. hieu ((ve cam) OR (ve cham)) duc ban thanh dai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) OR (su cac)) ky tang ma hoi. hieu ((ve cam) or (ve cham)) duc ban thanh dai cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((su sac) OR (su cac)) ky tang ma hoi. hieu ((ve cam) or (ve cham)) duc ban thanh dai cuu tre*.
