• Performing a fuzzy search may retrieve terms with similar spellings: (("sach mang vie nam.") OR ((("sach mang me nam.") OR ("sach man ve nam."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"sach mang vie nam.\") OR (((\"sach mang me nam.\") OR (\"sach man ve nam.\"))))".
• Removing quotes may allow a broader search: (( sach mang vie nam. ) OR ((( sach mang me nam. ) OR ( sach man ve nam. )))).
• Adding a wildcard symbol may retrieve word variants: (("sach mang vie nam.") OR ((("sach mang me nam.") OR ("sach man ve nam."))))*.
