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