#2. 测试ik分词
[root@daas4 plugins]# curl -XPOST http://localhost:9200/_analyze?pretty  -H 'Content-Type:application/json' -d '
{  
    "analyzer": "ik_max_word",
    "text": "我们是中国人"  
}'

result===>
{
  "tokens" : [
    {
      "token" : "我们",
      "start_offset" : 0,
      "end_offset" : 2,
      "type" : "CN_WORD",
      "position" : 0
    },
    {
      "token" : "中国人",
      "start_offset" : 3,
      "end_offset" : 6,
      "type" : "CN_WORD",
      "position" : 1
    },
    {
      "token" : "中国",
      "start_offset" : 3,
      "end_offset" : 5,
      "type" : "CN_WORD",
      "position" : 2
    },
    {

      "end_offset" : 6,
      "type" : "CN_WORD",
      "position" : 3
    }
  ]
}


#3. 创建索引，指定字段解析器和类型
[root@daas4 plugins]#  curl -XPUT localhost:9200/test_ik?pretty   -H "Content-Type: application/json" -d '
{
    "mappings": {
        "_default_": {
            "_all": {
                "enabled": false
            },
            "properties": {
                "tableSuffix": {
                    "index": true,
                    "store": true,
                    "type": "keyword"
                },
                "databaseName": {
                    "search_analyzer": "ik_max_word",
                    "analyzer": "ik_max_word",
                    "index": true,
                    "store": true,
                    "type": "text"
                },
                "tableId": {
                    "index": true,
                    "store": true,

                }
            }
        }
    }
}'

result==>

  "acknowledged" : true,
  "shards_acknowledged" : true
}
