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