Hi,

I have an performance issue regarding deleting from elasticsearch. I  
have 2 cases for deletion : 1. delete by term and 2. delete by \_id. The  
delete field is unique.

_1. DELETE by term_. The field I want to delete by term is mapped below :

.startObject(ListenerColumns.SUID.getColumnName())  
.field("type", "string")  
.field("index", "not\_analyzed")  
.field("store", false)  
.endObject()

```
Deleting query : 
        DeleteByQueryRequestBuilder prepareDelete = 

```

client.prepareDeleteByQuery(index);  
prepareDelete.setTypes(table);  
prepareDelete.setQuery(  
termQuery(ListenerColumns.SUID.getColumnName(),  
suidValue)  
);

The upper deleting is taking some time comparing with the next situation  
:

- 
  1. DELETE by \_id\*. The Suid is saved in \*\_id \*field.

My question is how should I configure the elasticsearch mapping for  
getting the same performance, in delete by term - _first case_, like in  
delete by \_id case - _second case_?

Thank you,  
Ciprian
