es之query_string查询

　　ES中接到请求后，通过查询解析器,解析查询串⽣成对应的查询。

1.指定单个字段查询

　　displayNameEn包含james或者curry的

　　也可是使用and

POST /nba/_search
{
  "query": {
    "query_string": {
      "default_field": "displayNameEn",
      "query": "james OR curry"
    }
  }
}

　　

2.指定多个字段查询

　　这里的先后顺序没有关系

POST /nba/_search
{
  "query": {
    "query_string": {
      "fields": [
        "displayNameEn","teamNameEn"
        ],
      "query": "Rockets and james"
    }
  }
}

　　效果：
