• Performing a fuzzy search may retrieve terms with similar spellings: hoc thien anh - anh nang qua dung ((((trong dan) OR (trong tan))) or (trong san)) toan tap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thien anh - anh nang qua dung ((((trong dan) OR (trong tan))) OR (trong san)) toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thien anh - anh nang qua dung ((((trong dan) OR (trong tan))) or (trong san)) toan tap*".
