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