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