• Performing a fuzzy search may retrieve terms with similar spellings: (("nat gian lang.") OR ((((("hau gian lang.") OR ("phan giang lang."))) OR ("au gian lang."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"nat gian lang.\") OR (((((\"hau gian lang.\") OR (\"phan giang lang.\"))) OR (\"au gian lang.\"))))".
• Removing quotes may allow a broader search: (( nat gian lang. ) OR ((((( hau gian lang. ) OR ( phan giang lang. ))) OR ( au gian lang. )))).
• Adding a wildcard symbol may retrieve word variants: (("nat gian lang.") OR ((((("hau gian lang.") OR ("phan giang lang."))) OR ("au gian lang."))))*.
