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