1. 新建一个索引，索引名为account

PUT account
{
  
}

2. 创建索引映射文件

其中text类型，es会自动分词，另外添加一个属性字段keyword，保存原来不分词的字段

PUT account/_mapping
{
  "properties": {
    "account_name": {
      "type": "text",
      "analyzer": "ik_smart",
      "fields": 
      { 
        "keyword": 
	{ 
             "type": "keyword", 
             "ignore_above": 256 
        } 
      }
    }
  }
}

3. 添加一条记录doc，并且设置id

PUT account/_doc/1
{
  "account_name": "程序员的早餐"
}

PUT account/_doc/4
{
  "account_name": "早餐的程序员"
}

4. 查询记录

GET account/_search
{
  "query": {
    "bool": {
      "should": [
        {
          "match": {
            "account_name.keyword": "早餐的程序员"
          }
        },
        {
          "match": {
            "account_name": "早餐的程序员"
          }
        }
      ]
    }
  }
}
