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