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