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