    3、创建空索引

      curl -XPUT http://127.0.0.1:9200/index_china

      

      

      在kibana的Dev Tools中用  PUT /index_american/

      

 

    4、创建映射

      curl -XPOST http://127.0.0.1:9200/index_china/fulltext/_mapping -d "{\"properties\": {\"content\": {\"type\": \"text\",\"analyzer\": \"ik_max_word\",\"search_analyzer\": \"ik_max_word\"}}}"

      

      或

      POST /index_american/fulltext/_mapping 

      {

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

      

    5、索引数据
