• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach v) or (sach va)) lang van hoa. hieu ve cam xuc van hanh vi ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach v) OR (sach va)) lang van hoa. hieu ve cam xuc van hanh vi ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach v) or (sach va)) lang van hoa. hieu ve cam xuc van hanh vi ((cua tre) OR (cua te))".
• Adding a wildcard symbol may retrieve word variants: te ((sach v) or (sach va)) lang van hoa. hieu ve cam xuc van hanh vi ((cua tre) OR (cua te))*.
