• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky ((dang ma) or (dang mau)) hoi. hieu ((ve cam) OR (ve cham)) xuc van hanh via cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((dang ma) OR (dang mau)) hoi. hieu ((ve cam) OR (ve cham)) xuc van hanh via cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((dang ma) or (dang mau)) hoi. hieu ((ve cam) OR (ve cham)) xuc van hanh via cua tre*".
