• Performing a fuzzy search may retrieve terms with similar spellings: vu sai ky ((tang van) or (trong van)) hoa. hieu ve cam tuc va danh te ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sai ky ((tang van) OR (trong van)) hoa. hieu ve cam tuc va danh te ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sai ky ((tang van) or (trong van)) hoa. hieu ve cam tuc va danh te ((cua tre) OR (cua te))".
• Adding a wildcard symbol may retrieve word variants: vu sai ky ((tang van) or (trong van)) hoa. hieu ve cam tuc va danh te ((cua tre) OR (cua te))*.
