• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ly) OR (sach lo)) lang ha hoi. hieu va cam luc va hanh di ((cua tu) or (cua tuc))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ly) OR (sach lo)) lang ha hoi. hieu va cam luc va hanh di ((cua tu) OR (cua tuc)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ly) OR (sach lo)) lang ha hoi. hieu va cam luc va hanh di ((cua tu) or (cua tuc))".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ly) OR (sach lo)) lang ha hoi. hieu va cam luc va hanh di ((cua tu) or (cua tuc))*.
