Hi !

I am practicing with the java api for elasticsearch and have a question for scroll api.

According to the online document, SearchType.SCAN should be defined for for setSearchType.

[https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-search-scrolling.html](https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-search-scrolling.html)

SearchResponse scrollResp = client.prepareSearch(test)  
.setSearchType(SearchType.SCAN)  
.setScroll(new TimeValue(60000))  
.setQuery(qb)  
.setSize(100).execute().actionGet(); //100 hits per shard will be returned for each scroll

However, according to the search type page, SearchType SCAN is deprecated from v 2.1.0.

[https://www.elastic.co/guide/en/elasticsearch/reference/current/search-request-search-type.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-request-search-type.html)

I have checked the code and SCAN is not included in the enum.

> <https://github.com/elastic/elasticsearch/blob/0f00c14afc8428a2a72c0b766d2171029dc8f6e1/core/src/main/java/org/elasticsearch/action/search/SearchType.java>

So, should I keep using the search type SCAN when I use the scroll api? If not , I appreciate if someone can educate me how to call the SearchResponse object for scroll api in correct way.

I agree that we should have updated the guide within this change: [https://github.com/elastic/elasticsearch/issues/12994](https://github.com/elastic/elasticsearch/issues/12994)

You can omit `.setSearchType(SearchType.SCAN)` but add a sort on `_doc`. Something similar to:

```auto
{
  "sort": [
    "_doc"
  ]
}

```

Do you want to contribute a documentation change?  
If so, you just have to propose changes for this file: [https://github.com/elastic/elasticsearch/blob/master/docs/java-api/search.asciidoc](https://github.com/elastic/elasticsearch/blob/master/docs/java-api/search.asciidoc)

I'll be happy to merge them.

Thanks for reporting!

Would you have the programmatic equivalent of that? Have a very similar use case to port to 5.2.1.
