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