• Performing a fuzzy search may retrieve terms with similar spellings: tu san ky ((sang lai) OR (mang lai)) roi. hieu cau cham ((su va) or (tu va)) hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ky ((sang lai) OR (mang lai)) roi. hieu cau cham ((su va) OR (tu va)) hanh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky ((sang lai) OR (mang lai)) roi. hieu cau cham ((su va) or (tu va)) hanh vi cua te*".
