Hi,

Now, one can define one or more mappings under the config/mappings  
directory in elasticsearch installation. Each time an index is created, the  
mappings will be applied to an index created automatically. Note, the  
mapping file name should be [mappingName.json]. More info here:  
[http://github.com/elasticsearch/elasticsearch/issues/issue/86](http://github.com/elasticsearch/elasticsearch/issues/issue/86).
