Hi,

Following mapping I have defined for one of my types.

{  
"user": {  
"properties": {  
"userid": {  
"dynamic":"false",  
"type": "string"  
},  
"password": {  
"dynamic":"false",  
"type": "string"

```
        }
    }
}

```

}

I want to make sure that documents that will be indexed must conform to the types I have defined in the ablove mapping. userid filed is string, so it should not accept numbers and this is why I have used dynamic property which is set to false. Also in the config file I have set index.mapper.dynamic to false. But this is not working for me when I index below document

{"userid":"u001","password":123}

It gets inserted. What may be the reason and how can I enforce type checking while indexing a document.

Thaks.
