hi,  
im wondering how this is possible, seems counter intuitive. lets say, there  
is a document in ES with id "1" and it has a field called "num\_actions" and  
the value is 1. in order to increment just the value of "num\_actions", i  
create another document, copy the original fields into new content builder  
and then make the "num\_actions" = 2. after i store the document in the  
index, it shows that it has 2 fields, both with the name "num\_actions" with  
values 1 and 2.

this is what i do -

```
    GetRequestBuilder grb = client.prepareGet(indexName, type, id);
    GetResponse response = grb.execute().actionGet();
    IndexRequestBuilder irb = client.prepareIndex(indexName, type, id);
    Map<String,Object> messageFieldMap = response.getSource();
    XContentBuilder xcb = jsonBuilder().startObject();

    xcb = populateXContentFromMessageFieldMap(messageFieldMap, xcb); //

```

helper method to copy everything from messageFieldMap to xcb  
xcb = xcb.field("num\_actions", 2);  
xcb = xcb.endObject();  
IndexResponse indexResponse =  
irb.setSource(xcb).execute().actionGet();

one option to avoid this issue is to be intelligent  
inside populateXContentFromMessageFieldMap by having an exclude list. are  
there any other ways?

thanks

What you end up doing there is generate a document with two fields with teh  
same name. You can always update the field on the Map you get back from the  
get response, and then pass that Map to the index request (it accepts a map  
as well as the source).
