• Performing a fuzzy search may retrieve terms with similar spellings: te san ky ((tang van) OR (trong van)) hoc. hieu van cam xuc va thanh ((lai cua) or (dai cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te san ky ((tang van) OR (trong van)) hoc. hieu van cam xuc va thanh ((lai cua) OR (dai cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te san ky ((tang van) OR (trong van)) hoc. hieu van cam xuc va thanh ((lai cua) or (dai cua)) tre*".
