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