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