Query on multi value field and only return hits Elasticsearch in Java

Elastic Stack Elasticsearch
1

I have a document set out like this:

{"thread_id":"1",

"thread_name":"Apple",

"created":"Wed Mar 11 2015",

"messages": [

{ "message_id": "1", "message": "Banana", "message_nick": "AdminTech"},

{ "message_id": "2", "message": "iPhone", "message_nick": "AdminTech"},

{ "message_id": "3", "message": "Mac", "message_nick": "AdminTech"},

{ "message_id": "4", "message": "Laptop", "message_nick": "AdminTech"}],

"thread_url":"1-Apple" }

I want to query on the thread_name field, which works, but I also want to
see if the keyword I am querying appears within the messages multi value
fields within message.

So for example, I want to query the word "Laptop". This document should
appear, but I only want the one field where the keyword matched, e.g.
message_id 4.

Here is the code I am using the query in Java:

QueryBuilder query = QueryBuilders.matchQuery(keyword, "thread_name");

QueryBuilder nestedQuery = QueryBuilders.matchQuery("messages.message",

keyword);

SearchRequestBuilder srb = client.prepareSearch("thread_and_messages") 

        .setSearchType(SearchType.DFS_QUERY_THEN_FETCH); 

srb.setQuery(QueryBuilders.boolQuery() 

        .should(query) 

        .should(nestedQuery) 

        .minimumShouldMatch("1")); 


SearchResponse threadResponse = srb.execute().actionGet(); 


SearchHit[] threadHits = threadResponse.getHits().getHits();

The code to retrieve the hits and place them within an object is here:

ArrayList messageIdAndMessage = (ArrayList) hit.get("messages");

ArrayList<TalkMessage> messages = new ArrayList<TalkMessage>(); 

FoundThreadAndMessage ftm = new FoundThreadAndMessage(); 

ftm.setId(Integer.parseInt(String.valueOf(hit.get("thread_id")))); 

ftm.setThreadName(String.valueOf(hit.get("thread_name"))); 

ftm.setCreated(String.valueOf(hit.get("created")));

Does anyone know if this query is correct, because at the moment I am
getting every single field back from the query.
