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