Hi everyone,  
I am having an Elastic search node(Elastic search 7.0.1).I have created an index called "property\_autocomplete" and pushed data from SQL to "property\_autocomplete" index.  
I forgot to add some fields.So i have reindexed "property\_autocomplete" to "property\_autocomplete\_1" using the below query:

POST \_reindex  
{  
"source": {  
"index": "property\_autocomplete"  
}  
},  
"dest": {  
"index": "property\_autocomplete\_1"  
}  
}  
After the reindex is complete, i have pushed one field alone to "property\_autocomplete\_1" using BulkIndexAsyn():

var descriptor = new BulkDescriptor();  
descriptor.Index(i =\> i  
.Index(indexName)  
.Type(typeName)  
.Id(id)  
.Document(obj));  
var bulkresult = esClient.Bulk(descriptor);

But the documents are overwritten instead of updating.  
Please suggest some solutions ?
