• Performing a fuzzy search may retrieve terms with similar spellings: te sach tu ((nano xa) OR (nano bac)) hoi. hieu va cam xuc ((vu dinh) or (van dinh)) vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tu ((nano xa) OR (nano bac)) hoi. hieu va cam xuc ((vu dinh) OR (van dinh)) vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tu ((nano xa) OR (nano bac)) hoi. hieu va cam xuc ((vu dinh) or (van dinh)) vi cua te*".
