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