To search an expression, simply put quotation marks around it.Example: A search for "1 franc" is more precise than 1 franc.
You may use an asterisk as a wildcard.Example: type "5 cent*" to find coins of 5 cents and 5 centimes.
Use a dash to exclude the coins matching with a word or expression.Example: Martin Luther -King
1 Tael = 10 Mace
1 Yuan = 100 Fen = 1000 Cashes
