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