• Performing a fuzzy search may retrieve terms with similar spellings: te sach tu ((lang van) or (hoang van)) hoa. thien van ((nam duc) OR (nam duoc)) va nang di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tu ((lang van) OR (hoang van)) hoa. thien van ((nam duc) OR (nam duoc)) va nang di cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tu ((lang van) or (hoang van)) hoa. thien van ((nam duc) OR (nam duoc)) va nang di cua te".
• Adding a wildcard symbol may retrieve word variants: te sach tu ((lang van) or (hoang van)) hoa. thien van ((nam duc) OR (nam duoc)) va nang di cua te*.
