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