Hope this helps to understand the elasticSearch Concept:  
String jsonString1 = "{" +  
""room":"livingroom","+  
""color":"red" "+  
"}";  
String jsonString2 = "{" +  
""room":"familyroom","+  
""color":"white" "+  
"}";  
String jsonString3 = "{" +  
""room":"kitchen","+  
""color":"blue" "+  
"}";

```
  String jsonString4 = "{" +
    "\"room\":\"bathroom\","+
    "\"color\":\"white\" "+
    "}";

  String jsonString5 = "{" +
    "\"room\":\"garage\","+
    "\"color\":\"blue\" "+
    "}";

  Node node = null;
  node = NodeBuilder.nodeBuilder().node();

  Client client = node.client();
  client.prepareIndex("house", "room", String.valueOf("1")).setSource(jsonString1).execute().actionGet();
  client.prepareIndex("house", "room", String.valueOf("2")).setSource(jsonString2).execute().actionGet();
  client.prepareIndex("house", "room", String.valueOf("3")).setSource(jsonString3).execute().actionGet();
  client.prepareIndex("house", "room", String.valueOf("4")).setSource(jsonString4).execute().actionGet();
  client.prepareIndex("house", "room", String.valueOf("5")).setSource(jsonString5).execute().actionGet();

  QueryBuilder queryBuilder = QueryBuilders.termQuery("color", "white");
  SearchRequestBuilder searchRequestBuilder = client.prepareSearch("house");
  searchRequestBuilder.setTypes("room");
  searchRequestBuilder.setSearchType(SearchType.DEFAULT);
  searchRequestBuilder.setQuery(queryBuilder);
  searchRequestBuilder.setFrom(0).setSize(60).setExplain(true);
  SearchResponse resp = searchRequestBuilder.execute().actionGet();
  for (SearchHit hit : resp.getHits())
    System.out.println("Hit ID: "+hit.getId());
  node.close();
}
catch (Exception e)
{
  e.printStackTrace();  
}

```

Output of this hits :  
Hit ID: 4  
Hit ID: 2

Hi,

thanks for the effort!

Couple of comments about the code:

- in many cases it is better to use jsonBuilder instead of creating json  
String manually
- if you do search right after the data is indexed it is better to call  
refresh to make sure all the data will be visible to the search

I took your idea and turned it into a little more polished code (I also  
added some syntax sugar and some init and cleanup code), it can be found  
here:

Regards,  
Lukas

Thank you for your code sample. Now, I get time out error after creating an index ( right after this code)  
client.prepareIndex("house", "room", String.valueOf("1")).setSource(jsonString1).execute().actionGet();

org.elasticsearch.action.UnavailableShardsException: [house][0] [2] shardIt, [0] active : Timeout waiting for [1m], request: index {[house][room][4], source[{"room":"bathroom","color":"white" }]}

Any suggestions?
