• Performing a fuzzy search may retrieve terms with similar spellings: (("ngo tang truong") or ((("ngo thanh trong") or ((("ngo dang thuong") OR ("ngo dong thuong"))))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("ngo tang truong") OR ((("ngo thanh trong") OR ((("ngo dang thuong") OR ("ngo dong thuong"))))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"ngo tang truong\") or (((\"ngo thanh trong\") or (((\"ngo dang thuong\") OR (\"ngo dong thuong\"))))))*".
• Removing quotes may allow a broader search: (( ngo tang truong ) or ((( ngo thanh trong ) or ((( ngo dang thuong ) OR ( ngo dong thuong ))))))*.
