• Performing a fuzzy search may retrieve terms with similar spellings: ((te sach) or (nuoc sach)) y ((lang xa) OR (lang van)) hoi. hieu ve chat tu van hanh di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (nuoc sach)) y ((lang xa) OR (lang van)) hoi. hieu ve chat tu van hanh di cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (nuoc sach)) y ((lang xa) OR (lang van)) hoi. hieu ve chat tu van hanh di cua te*".
