• Performing a fuzzy search may retrieve terms with similar spellings: (((("thai binh khoa luan") or ("tai chinh thuat luan"))) or ((("phai sinh hoat lan") OR ("pham minh hoat lan"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("thai binh khoa luan") OR ("tai chinh thuat luan"))) OR ((("phai sinh hoat lan") OR ("pham minh hoat lan")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"thai binh khoa luan\") or (\"tai chinh thuat luan\"))) or (((\"phai sinh hoat lan\") OR (\"pham minh hoat lan\"))))".
• Removing quotes may allow a broader search: (((( thai binh khoa luan ) or ( tai chinh thuat luan ))) or ((( phai sinh hoat lan ) OR ( pham minh hoat lan )))).
• Adding a wildcard symbol may retrieve word variants: (((("thai binh khoa luan") or ("tai chinh thuat luan"))) or ((("phai sinh hoat lan") OR ("pham minh hoat lan"))))*.
