• Performing a fuzzy search may retrieve terms with similar spellings: te sach ly ((hang xa) OR (hoang xa)) hoi. hieu va ((phan duc) or (pham duy)) va lang vi cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ly ((hang xa) OR (hoang xa)) hoi. hieu va ((phan duc) OR (pham duy)) va lang vi cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ly ((hang xa) OR (hoang xa)) hoi. hieu va ((phan duc) or (pham duy)) va lang vi cua tu".
• Adding a wildcard symbol may retrieve word variants: te sach ly ((hang xa) OR (hoang xa)) hoi. hieu va ((phan duc) or (pham duy)) va lang vi cua tu*.
