Hi ,  
I have a situation where i have to use the existing field value as an \_id ,as described here [https://www.elastic.co/guide/en/elasticsearch/reference/1.4/mapping-id-field.html](https://www.elastic.co/guide/en/elasticsearch/reference/1.4/mapping-id-field.html)  
I know it is not supported in latest versions.  
and we are supposed to use **/index/type/\_id** for creating own id.  
But in application i am working on the \_id will be generated by third party app and will be stored in \_source ,i should be using that as an \_id.  
Is there any way to use existing field value as \_id.

Thanks
