Hi,

I am trying to force purge document immediately after deleting . I am unable to perform it without full re-indexing.  
I deleted 3 document in total of 10, but the total document in ES still shows 10.  
Following are the result of various api calls :  
**\_stats** --\>  
"indexing": {  
"index\_total": 22,  
"index\_time\_in\_millis": 445,  
"index\_current": 0,  
"index\_failed": 68,  
"delete\_total": 3,  
"delete\_time\_in\_millis": 2,

I am invoking forcemerge in following way :  
private void optimizeIndex(String index, int maxNumSegments) {  
Client client = (Client)SpringUtil.getBean("searchClient");  
final ForceMergeRequest request = client.admin().indices().prepareForceMerge(index).setMaxNumSegments(maxNumSegments).setOnlyExpungeDeletes(true).setFlush(true).request();

```
        // Using a specific timeout to override the global Elasticsearch request timeout
        ForceMergeResponse forceMergeResponse = client.admin().indices().forceMerge(request).actionGet();
}

```

I am calling this function as soon as I delete documents.  
Not sure what I am doing wrong.

Thanks,  
RAH

Did you run a refresh before running the forcemerge?
