I am completely new to Elastic Search. I have figured out enough that I can  
retrieve jsons from our cluster with:

-bash-3.2$ curl -XGET [http://10.10.1.7:9200/twitter-sept/\_search](http://10.10.1.7:9200/twitter-sept/_search) -d  
'{"query":{"bool":{"must":[{"term":{"tweet":"elastic"}}],"must\_not":[],"should":[]}},"from":0,"size":50,"sort":[],"facets":{}}'

Since most of my code is in Java I figured things would be easier if I used  
the Java API. I am completely stumped on how to do it. The guide  
[http://www.elasticsearch.org/guide/reference/java-api/search.html](http://www.elasticsearch.org/guide/reference/java-api/search.html) is  
confusing. What are all those classes? Where are the javadocs? Is there a  
simple example somewhere that explains how I can reproduce the above  
command in Java? Do I need a TransportClient, a SearchSourceBuilder,  
ImmutableSettings?

Thanks!

I can finally get some basic searches working from Java now. After looking  
through some of that code I can run the simple example below. I'm sure  
there are reasons I should bother with TransportClients, setting cluster  
names (ours is not "elasticsearch"), etc.. But for just getting started  
and making sure things work the code in the tutorial really helped. I wish  
the guide at  
[Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/java-api/search.html) had  
actual code and not just snippets.

public static void main(String args){  
Node node = NodeBuilder.nodeBuilder().node();  
Assert.assertNotNull(node);  
Assert.assertFalse(node.isClosed());

QueryBuilder qb = QueryBuilders.termQuery("tweet", "elastic");

SearchResponse sr = node.client().prepareSearch()  
.setQuery(qb)  
.execute()  
.actionGet();  
Assert.assertNotNull(sr);  
Assert.assertNotNull(sr.getHits());  
Assert.assertTrue(sr.getHits().getTotalHits() \> 0);  
java.util.Iterator hit\_it = sr.getHits().iterator();  
while(hit\_it.hasNext()){  
SearchHit hit = hit\_it.next();  
System.out.println(hit.getSourceAsString());  
}  
}

Hi Ryan! I heartily recommend reading the tests in IntelliJ. That's  
how I usually figure out what was intended in the Java API. The  
coverage of the search API is pretty robust.

Hey David,

I'm looking at the code now and I see lots of TODOs and nulls, but no  
actual indexing. Perhaps that code needs to be cleaned up?

So where is a good java example showing how to use the java api to do a  
simple and condition. I can get this to work work fine with curl but how do  
I use the java api to implement it.

curl -XPOST 10.20.71.30:9200/sessionmsg/\_search?pretty -d '{  
"query": {  
"bool": {  
"must": [  
{  
"term": {  
"roomid": "7087"  
}  
},  
{  
"term": {  
"sessionid": "55622"  
}  
}  
]  
}  
}  
}  
}'

how can I implement the above with this kind of call?  
SearchResponse response = client.prepareSearch("sessionmsg")  
.setSearchType(SearchType.DFS\_QUERY\_THEN\_FETCH)
