elasticsearch - 使用 Transport Client 创建索引时，我应该如何将字段的分析指定为 not_analyzed

Question

我正在使用 elasticsearch-6.1.1。由于 CreateIndexRequest api 不是由 JavaHighLeve client-6.1.1 提供的，我尝试通过使用此处给出的 TransportClient 来创建索引:( https://www.elastic.co/guide/en/elasticsearch/client/java-rest/master/_changing_the_application_8217_s_code.html )代码是:

public class IndexOperations {

    RestHighLevelClient client ;
    public IndexOperations(RestHighLevelClient client){
        this.client = client ; 
    }

    public void indexOperations()throws UnknownHostException,IOException  {

        TransportClient transportClient = new PreBuiltTransportClient(Settings.EMPTY)
                .addTransportAddress(new TransportAddress(InetAddress.getByName("localhost"),9300));


        String mapping = XContentFactory.jsonBuilder()
                        .startObject()
                            .startObject("delllogfiles")
                                .startObject("properties")

                                        .field("index","not_analyzed")
                                    .endObject()

        CreateIndexResponse createIndexResponse = transportClient.admin().indices()
                                                    .prepareCreate("logfiles")
                                                    .addMapping("delllogfiles",mapping,XContentType.JSON)
                                                    .get();

        System.out.println("finally index created "+createIndexResponse.isAcknowledged());
        transportClient.close();

当运行代码时，我得到一个异常:

Exception in thread "main" MapperParsingException[Failed to parse mapping [delllogfiless]: Could not convert [message.index] to boolean]; nested: IllegalArgumentException[Could not convert [message.index] to boolean]; nested: IllegalArgumentException[Failed to parse value [not_analyzed] as only [true] or [false] are allowed.];

如何在使用 TransportClient 时将字段的分析器设置为 not_analyzed？

来自elastic search 5的索引属性只有两个选项

• 正确
• 错误

对于 not_analyzed 字符串字段，使用字段类型 keyword 而不是默认为 not_analyzed 的 text
