2.创建mapping映射

curl -H  'Content-Type: application/json' -XPOST 'http://10.47.0.96:9200/data_archives/_mapping' -d'
{
    "properties": {
        "reporterName": {
            "type": "text",
            "analyzer": "ik_max_word",
            "search_analyzer": "ik_max_word"
        }
    }
}'

3.查看映射

curl -H  'Content-Type: application/json' -XGET 'http://10.47.0.96:9200/data_archives/_mapping?pretty'

4.初始化文档

curl -H  'Content-Type: application/json' -XPOST 'http://10.47.0.96:9200/data_archives/_doc/1' -d'
{
  "reporterId": "1",
  "reporterName": "张三",
