• Performing a fuzzy search may retrieve terms with similar spellings: vu cac ky ((lang van) OR (dang van)) hoa. hieu ((ve cac) or (va cac)) loc va tinh ca cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu cac ky ((lang van) OR (dang van)) hoa. hieu ((ve cac) OR (va cac)) loc va tinh ca cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu cac ky ((lang van) OR (dang van)) hoa. hieu ((ve cac) or (va cac)) loc va tinh ca cua tre*".
