sorry, im newbie and i have one question:  
i created one index like this  
curl -XPUT '[http://localhost:9200/users/user/1](http://localhost:9200/users/user/1)' -d '{  
"user" : "test1",  
"password" : "test2"  
}'  
And i have something like this in mapping 😄  
"user": {  
"properties": {  
"password": {  
"type": "string"  
},  
"user": {  
"type": "string"  
}  
}  
}

My question is : Have anyway change analyzer after created index ? Like i want change default analyzer to one analyzer i have.  
"user": {  
"type": "string",  
"analyzer" :"xxx";  
}

Thanks for your help!

You need to reindex.
