• Performing a fuzzy search may retrieve terms with similar spellings: hoc anh my nang ma hoi. ((hieu ve) OR (hieu van)) ((cam xuc) or (cao duc)) ban hanh hai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc anh my nang ma hoi. ((hieu ve) OR (hieu van)) ((cam xuc) OR (cao duc)) ban hanh hai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc anh my nang ma hoi. ((hieu ve) OR (hieu van)) ((cam xuc) or (cao duc)) ban hanh hai cua te".
• Adding a wildcard symbol may retrieve word variants: hoc anh my nang ma hoi. ((hieu ve) OR (hieu van)) ((cam xuc) or (cao duc)) ban hanh hai cua te*.
