Could someone share a working example of using the Java API to define type mappings? I'm trying things like: Settings.Builder indexSettings = ImmutableSettings.settingsBuilder().loadFromSource( XContentFactory.jsonBuilder() .startObject() .startObject("settings") .startObject("index") .field("number\_of\_shards","BOGUS") .endObject() .endObject() .startObject("mappings") .startObject("my\_type\_name") .startObject("sequence") .field("type", "boolean") .endObject() .startObject("message.text") .field("type", "string") .field("index", "no") .endObject() .endObject() .endObject() .endObject().string()); CreateIndexResponse createIndexResponse = client.admin().indices() .prepareCreate(newSlice).setSettings(indexSettings) .execute().actionGet(); I haven't managed to twiddle the builder structure such that they take effect. E.g. message.text is searchable despite not being index, sequence accepts numbers despite being boolean, and number\_of\_shards being set to BOGUS doesn't produce any errors. Thanks -Lorrin ---

Hi David, That helped, thanks. After getting the builder stuff working following the example, I switched over to supplying the settings as a JSON string with the following command: CreateIndexResponse createIndexResponse = client.admin().indices() .prepareCreate(indexName) .setSettings(elasticSearchSettings) .addMapping(elasticSearchType, elasticSearchMappings) .execute().actionGet(); where elasticSearchSettings is: { "index" : { "number\_of\_shards" : 2, "number\_of\_replicas" : 1 } } and elasticSearchMappings is in the format { "" : { "properties" : { "\" : { "type" : ... }, ... } } I wasn't able to apply settings using a nested Java Map\ structure, but I'm happy with supplying the JSON.

This was quite helpful. I do have one question though. Is elasticSearchMappings of type Settings?
