• Performing a fuzzy search may retrieve terms with similar spellings: thuat lanh ky ((nang ma) or (sang ma)) hoa. hieu ((ve cam) OR (ve cac)) xuc va dinh vi cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat lanh ky ((nang ma) OR (sang ma)) hoa. hieu ((ve cam) OR (ve cac)) xuc va dinh vi cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat lanh ky ((nang ma) or (sang ma)) hoa. hieu ((ve cam) OR (ve cac)) xuc va dinh vi cua tu*".
