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