• Performing a fuzzy search may retrieve terms with similar spellings: (((("kinh tu ngu nghia.") OR ("dinh tu ngu nghia."))) OR ("kinh tu ngu nghien."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"kinh tu ngu nghia.\") OR (\"dinh tu ngu nghia.\"))) OR (\"kinh tu ngu nghien.\"))".
• Removing quotes may allow a broader search: (((( kinh tu ngu nghia. ) OR ( dinh tu ngu nghia. ))) OR ( kinh tu ngu nghien. )).
• Adding a wildcard symbol may retrieve word variants: (((("kinh tu ngu nghia.") OR ("dinh tu ngu nghia."))) OR ("kinh tu ngu nghien."))*.
