Analyzer not found exception while creating an index with mapping and settings

Question

Hi I am using Elastic Search elasticsearch-0.90.2 version. I am trying to map analyzer with custom analyzer using jsonBuilder, while creating index, it is throwing exception like analyzer not found.

Setting :-

       XContentBuilder settings = XContentFactory.jsonBuilder()
            .startObject()
                 .startObject("settings")
                      .startObject("analysis")
                           .startObject("analyzer")                 
                                .startObject("search_analyzer")             
                                      .field("tokenizer", "ngram_specification")
                                      .field("type", "custom")
                                      .field("filter", new String[]{ "ngram_specification"})
                                .endObject()
                            .endObject()
                            .startObject("ngram_specification")
                                 .field("type", "nGram")
                                 .field("min_gram", "2")
                                 .field("max_gram", "5")
                            .endObject()    
                      .endObject()
                 .endObject()
            .endObject();

Mapping :-

  XContentBuilder mapping = XContentFactory.jsonBuilder()

      .startObject()
             .startObject("sample")
                 .startObject("properties")
                     .startObject("email").field("type", "string").field("index", "analyzed").field("analyzer", "search_analyzer")
                     .endObject()
                 .endObject()
            .endObject()
      .endObject();

Creating Index like this :-

        CreateIndexRequest indexRequest = new CreateIndexRequest(indexName);
        indexRequest.settings(settings);
        indexRequest.mapping("sample", mapping);
        CreateIndexResponse response = client.admin().indices().create(indexRequest).actionGet();

Exception :

Can anyone please tell the mistake in this approach?

I found the solution for this. In Settings, if you use "index" instead of "Settings" then it will work fine.

This is wrong:

XContentBuilder settings = XContentFactory.jsonBuilder()
    .startObject()
         .startObject("settings") // "settings"
              .startObject("analysis")

but this does:

XContentBuilder settings = XContentFactory.jsonBuilder()
    .startObject()
         .startObject("index") // "index" instead of "settings"
              .startObject("analysis")

You can check if your settings are correctly applied using the Get Settings API.

I think you analyzer has not been created because of an error in your settings configuration. The tokenizer entry is probably missing. Here is a corrected version :

  XContentBuilder settings = XContentFactory.jsonBuilder()
        .startObject()
             .startObject("settings")
                  .startObject("analysis")
                       .startObject("analyzer")                 
                            .startObject("search_analyzer")             
                                  .field("tokenizer", "ngram_specification")
                                  .field("type", "custom")
                                  .field("filter", new String[]{ "ngram_specification"})
                            .endObject()
                        .endObject()
                        .startObject("tokenizer")
                             .startObject("ngram_specification")
                                  .field("type", "nGram")
                                  .field("min_gram", "2")
                                  .field("max_gram", "5")
                             .endObject()    
                        .endObject()    
                  .endObject()
             .endObject()
        .endObject();

Good one! At first glance I think the filter is missing too. — javanna, Jul 12 '13 at 11:24
