I'm trying to add a tokenizer and three analyzers to my index at creation time.  
Here's the code:

```auto
client.admin().indices().prepareCreate(indexName).setSettings(Settings.builder().loadFromSource(jsonBuilder()
			        .startObject()
				        .startObject("analysis")
					        .startObject("tokenizer")
						        .startObject("username_tokenizer")
				                    .field("type", "nGram")
				                    .field("min_gram", 1)
				                    .field("max_gram", 80)
				                .endObject()
					        .endObject()
				            .startObject("analyzer")
				                .startObject("string_lowercase")
				                    .field("type", "custom")
				                    .field("tokenizer", "keyword")
				                    .field("filter", new String[]{"lowercase"})
				                .endObject()
				            .endObject()
				            .startObject("analyzer")
				                .startObject("email")
				                    .field("type", "custom")
				                    .field("tokenizer", "uax_url_email")
				                    .field("filter", new String[]{"standard","lowercase","stop"})
				                .endObject()
				            .endObject()
				            .startObject("analyzer")
				                .startObject("username")
				                    .field("type", "custom")
				                    .field("tokenizer", "username_tokenizer")
				                    .field("filter", new String[]{"standard","lowercase"})
				                .endObject()
				            .endObject()
				        .endObject()
				    .endObject().string(), XContentType.JSON))
			.execute().actionGet();

```

I'm getting the following error:

```auto
Caused by: com.fasterxml.jackson.core.JsonParseException: Duplicate field 'analyzer'

```

I suspect it may have something to do with creating multiple analyzers in the same JSON object. Is there a way to do this, or should I send each analyzer individually after creating the index? If so, what is the syntax to do this?

It's wrong. You should write something like:

```auto
				            .startObject("analyzer")
				                .startObject("analyzer1")
				                    .field("type", "custom")
				                    .field("tokenizer", "keyword")
				                    .field("filter", new String[]{"lowercase"})
				                .endObject()
				                .startObject("analyzer2")
				                    .field("type", "custom")
				                    .field("tokenizer", "keyword")
				                    .field("filter", new String[]{"lowercase"})
				                .endObject()
				                .startObject("analyzer3")
				                    .field("type", "custom")
				                    .field("tokenizer", "keyword")
				                    .field("filter", new String[]{"lowercase"})
				                .endObject()
				            .endObject()

```
