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