• Performing a fuzzy search may retrieve terms with similar spellings: so sang ky ((((tang ma) OR (tang van))) or (sang ma)) hoi. hieu va chat xuc cac dan dat cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sang ky ((((tang ma) OR (tang van))) OR (sang ma)) hoi. hieu va chat xuc cac dan dat cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sang ky ((((tang ma) OR (tang van))) or (sang ma)) hoi. hieu va chat xuc cac dan dat cua tu*".
