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