• Performing a fuzzy search may retrieve terms with similar spellings: toc sach xu ((lang xa) or (lang ha)) hoi. lieu ((va cam) OR (va cao)) xuc anh tuan vi cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach xu ((lang xa) OR (lang ha)) hoi. lieu ((va cam) OR (va cao)) xuc anh tuan vi cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach xu ((lang xa) or (lang ha)) hoi. lieu ((va cam) OR (va cao)) xuc anh tuan vi cua tu".
• Adding a wildcard symbol may retrieve word variants: toc sach xu ((lang xa) or (lang ha)) hoi. lieu ((va cam) OR (va cao)) xuc anh tuan vi cua tu*.
