elasticSearch请求正文搜索

发布时间：2021-09-02 19:16:12编辑：雪饮阅读（）

 ElasticSearch的请求正文搜索区别于前面所接触的URI搜索，URI搜索在地址栏控制参数。

请求正文搜索顾名思义，请求的匹配语法都在请求正文中。
一个最常见的请求正文搜索如：
http://localhost:9200/schools/_search get
请求正文：
{
   "query":{
      "query_string":{
         "query":"up"
      }
   }
}
响应正文：
{
    "took": 51,
    "timed_out": false,
    "_shards": {
        "total": 1,
        "successful": 1,
        "skipped": 0,
        "failed": 0
    },
    "hits": {
        "total": {
            "value": 1,
            "relation": "eq"
        },
        "max_score": 1.2039728,
        "hits": [
            {
                "_index": "schools",
                "_type": "school",
                "_id": "3",
                "_score": 1.2039728,
                "_source": {
