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