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