Hi,

How to make my search response to give all the documents matched to the relevant query without using any  
setSize(10) with predefined value.  
How can I achieve this????

**Right now am using :**  
response = client.prepareSearch(index).setTypes(type)  
.setQuery(QueryBuilders.matchAllQuery()).setSize(10).execute()  
.actionGet();

Here when I would like to get the complete response and i dont know the size in advance, then how can I achieve the complete response without size declaration. (or) any other way to get the complete data??

Perhaps scan and scroll is what you want? [https://www.elastic.co/guide/en/elasticsearch/guide/current/scan-scroll.html](https://www.elastic.co/guide/en/elasticsearch/guide/current/scan-scroll.html)

Here is a link to the Java API documentation on using the scroll API: [https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/scrolling.html](https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/scrolling.html)
