创建索引时如何解决映射问题？

Question

当我想在Elasticsearch中创建索引，然后使用putmappings函数设置映射时，失败并得到{“ mappings”：{}}。然后我使用ES6.6.0和Jest Client。如何更正我的代码？

//create index
jestResult = client.execute(new CreateIndex.Builder(indexName).settings(settings).build());

mappingsBuild.startObject()
         .startObject(indexName)
         .startObject("properties")                 
         .startObject("content").field("type","text")
         .field("analyzer","ik_smart")
         .field("search_analyzer","ik_max_word").endObject()
         .endObject()
         .endObject();

PutMapping putMapping = new PutMapping.Builder(indexName,typeName,mappings).build();

jestResult = client.execute(putMapping);

我希望有映射：

"mappings": { 
  "typeName": { 
    "properties": { 
      "content": { 
         "search_analyzer": "ik_smart",
         "analyzer": "ik_max_word",
         "type": "text"
      }
    }
  }
}

不是“映射”：{}
