When I'm feeding a document with a long-value (Java API) and  
retrieving the _source_ of this doc back I'm getting an integer value.  
What am I doing wrong? (See append code)

Kind Regards,  
Peter.

Node node = nodeBuilder().  
local(true).  
settings(ImmutableSettings.settingsBuilder().  
put("number\_of\_shards", 3).  
put("number\_of\_replicas", 1).  
put("gateway.type", "none").  
build()).  
build().  
start();

```
    String indexName = "tweetindex";
    String indexType = "tweet";

```

// load json from string  
String fileAsString = "{"  
+ ""tweet" : {"  
+ " "properties" : {"  
+ " "longval" : { "type" : "long",  
"null\_value" : -1}"  
+ "}}}";

```
    Client client = node.client();

    // create index
    CreateIndexResponse rsp = client.admin().indices().
            create(new

```

CreateIndexRequest(indexName).mapping(indexType, fileAsString)).  
actionGet();  
client.admin().cluster().health(new  
ClusterHealthRequest(indexName).waitForYellowStatus()).actionGet();

```
    XContentBuilder docBuilder =

```

XContentFactory.jsonBuilder().startObject();  
docBuilder.field("longval", 124L);  
docBuilder.endObject();

```
    // feed previously created doc
    IndexRequestBuilder irb = client.prepareIndex(indexName,

```

indexType, "1").  
setConsistencyLevel(WriteConsistencyLevel.DEFAULT).  
setSource(docBuilder);  
irb.execute().actionGet();

```
    // make doc available for sure
    client.admin().indices().refresh(new

```

RefreshRequest(indexName)).actionGet();

```
    // query for this doc
    XContentQueryBuilder qb = QueryBuilders.matchAllQuery();
    TermFilterBuilder fb = FilterBuilders.termFilter("longval",

```

124L);  
SearchRequestBuilder srb = client.prepareSearch(indexName).  
setSearchType(SearchType.QUERY\_AND\_FETCH).  
setQuery(QueryBuilders.filteredQuery(qb, fb));  
SearchResponse response = srb.execute().actionGet();  
System.out.println("failed shards:" +

[0].getSource().get("longval");  
System.out.println("longval:" + num);//longval:124  
System.out.println("longval.getClass:" + num.getClass());//  
longval.getClass:class java.lang.Integer  
node.stop();

Its basically the parser, since it can't tell from the json parsed if its long or not, it allocates the relevant data type depending on the value. It has nothing to do with the mapping itself (ES uses jackson to parse the json into a Map of Maps. I suggest you simply treat it as a Number, and call longValue.

ah, ok. thought it gets into the source via long + then it gets out  
via long.

Thanks for the clarification!
