hello ,I use the search API,just want to get some fileds and set the addFields method.like this,  
client.prepareSearch(index).setTypes(type).addFields(fields).setQuery(queryBuilder).setSize(sizeLimit).setExplain(true).get();  
but when I get the result that is null.  
for(SearchHit hit:response.getHits().getHits()){  
Map\<String, Object\> hitsMap = hit.getSource();  
[log.info](http://log.info)("["+hitsMap+"]");  
}  
I try to set the setSearchType(SearchType.QUERY\_AND\_FETCH) method ,or set the QUERY\_THEN\_FETCH ....but it does not work.  
version:2.3.0

Actually I ignore something. When we set the addFields method,we can't fetch the result use that kind of method. It should be like this.

[Code]:  
for(SearchHit hit:response.getHits().getHits()){  
if( null != fields ){  
Set\<Entry\<String, SearchHitField\>\> fieldEntry = hit.getFields().entrySet();  
JSONObject json = new JSONObject();  
for(Entry\<String, SearchHitField\> entry:fieldEntry){  
json.put(entry.getValue().getName(), entry.getValue().getValue());  
}  
[log.info](http://log.info)("["+json+"]");   
}else{  
[log.info](http://log.info)(hit.getSourceAsString());  
}  
}  
}
