Hi all,

A couple questions on mapping definition. I run ES embedded in my  
application nodes.

1. Using the java API only, no source file, how do you initialize your  
mappings? What I want to do is change the "default" mapping so that  
all indexing and query parsing is done with this configuration.

2. When I index and build my JSon entity representation, I want to  
specify the tokenize and store attribute for each field individually.

3. Is there some example code I can check somewhere?

Here's what I have right now but I'm getting a 'mapping type is  
missing' exception...

Thanks for helping...

```
    // Initialize the ES embedded client.

    // Set path.data from the app.lucene.dir setting in

```

application.properties.

```
    Properties esProperties = new Properties();
    esProperties.putAll(configuration);
    esProperties.setProperty("path.data",

```

configuration.getProperty(ConfigurationConstants.PROP\_APP\_LUCENE\_DIR));

```
    Settings settings =

```

ImmutableSettings.settingsBuilder().put(esProperties).build();  
elasticSearchNode =  
NodeBuilder.nodeBuilder().settings(settings).node();  
elasticSearchClient = elasticSearchNode.client();

```
    // Default configuration.

    XContentBuilder mappings = null;
    try
    {
        mappings = XContentFactory.jsonBuilder();

```

mappings.startObject().startObject("analysis").startObject("analyzer").startObject("default")  
.field("type", "custom").field("tokenizer",  
"whitespace")  
.field("filter", new String[] { "snowball",  
"standard", "lowercase" }).endObject().endObject()  
.endObject().endObject();

```
        logger.info(mappings.string());
    }
    catch (IOException e)
    {
        ValidateState.fail();
    }

    PutMappingRequestBuilder mappingRequest =

```

elasticSearchClient.admin().indices().preparePutMapping("default");  
mappingRequest.setSource(mappings);  
PutMappingResponse mappingResponse =  
mappingRequest.execute().actionGet();

You put the index configuration as a mapping for a type. Mappings are for document types, index settings are for things like custom analyzers.

Yeah, that makes sense and... it works!!! 😉

Thanks!

Here's how I redefined the default analyser for those that may have  
the same need:

```
    XContentBuilder indexSettings = null;
    try
    {
        indexSettings = XContentFactory.jsonBuilder();

```

indexSettings.startObject().startObject("index").startObject("analysis").startObject("analyzer")  
.startObject("default").field("type",  
"custom").field("tokenizer", "whitespace")  
.field("filter", new String[] { "asciifolding",  
"lowercase" }).endObject().endObject().endObject()  
.endObject().endObject();

```
        logger.info(indexSettings.string());

        UpdateSettingsRequestBuilder settingsRequest =

```

elasticSearchClient.admin().indices()  
.prepareUpdateSettings();  
settingsRequest.setSettings(indexSettings.string());  
UpdateSettingsResponse settingsResponse =  
settingsRequest.execute().actionGet();  
}  
catch (IOException e)  
{  
ValidateState.fail();  
}
