• Performing a fuzzy search may retrieve terms with similar spellings: (("trieu minh tinh.") OR ((("trieu tinh tinh.") OR ("trieu tinh ninh."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"trieu minh tinh.\") OR (((\"trieu tinh tinh.\") OR (\"trieu tinh ninh.\"))))".
• Removing quotes may allow a broader search: (( trieu minh tinh. ) OR ((( trieu tinh tinh. ) OR ( trieu tinh ninh. )))).
• Adding a wildcard symbol may retrieve word variants: (("trieu minh tinh.") OR ((("trieu tinh tinh.") OR ("trieu tinh ninh."))))*.
