• Performing a fuzzy search may retrieve terms with similar spellings: (((("hoi nhan hau.") OR ("hoi nhan ha."))) OR ("doi nhan cau."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"hoi nhan hau.\") OR (\"hoi nhan ha.\"))) OR (\"doi nhan cau.\"))".
• Removing quotes may allow a broader search: (((( hoi nhan hau. ) OR ( hoi nhan ha. ))) OR ( doi nhan cau. )).
• Adding a wildcard symbol may retrieve word variants: (((("hoi nhan hau.") OR ("hoi nhan ha."))) OR ("doi nhan cau."))*.
