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