• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty ((((nang xa) OR (mang xa))) or (lang xa)) hoi. hieu ve cac luc va danh di cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((((nang xa) OR (mang xa))) OR (lang xa)) hoi. hieu ve cac luc va danh di cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((((nang xa) OR (mang xa))) or (lang xa)) hoi. hieu ve cac luc va danh di cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ty ((((nang xa) OR (mang xa))) or (lang xa)) hoi. hieu ve cac luc va danh di cua tre*.
