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