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