文档查询
主键查询
从前面的操作来看,其实可以很好的猜想根据主键查询的url地址一个和主键添加文档的URL地址一样,只是请求的方法得使用GET
请求。例如查询1001
的文档,URL地址:http://127.0.0.1:9200/shopping/_doc/1001
返回的结果为:
{
"_index": "shopping",
"_type": "_doc",
"_id": "1001",
"_version": 1,
"_seq_no": 1,
"_primary_term": 1,
"found": true,
"_source": {
"title": "水星家纺被子夏季空调被 夏凉被夏天被子双人夏被被芯学生宿舍被子200*230cm",
"category": "床上用品",
"image": "https://img11.360buyimg.com/n7/jfs/t1/191056/14/24248/144443/62767f75E23ccafc4/5110691845cfa4cf.jpg",
"price": 139.0
}
}
如果我们给出的id
是不存在的,例如:http://127.0.0.1:9200/shopping/_doc/2001
返回内容就会变为:
{
"_index": "shopping",
"_type": "_doc",
"_id": "2001",
"found": false
}
全查询
全查询就是查询所有的文档信息:
请求的url地址:http://127.0.0.1:9200/shopping/_search/1001
响应结果:
{
"took": 35,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"skipped": 0,
"failed": 0
},
"hits": {
"total": {
"value": 2,
"relation": "eq"
},
"max_score": 1.0,
"hits": [
{
"_index": "shopping",
"_type": "_doc",
"_id": "6m6EooAB7B_-m9JH0tpA",
"_score": 1.0,
"_source": {
"title": "水星家纺 60S长绒棉贡缎床上四件套 酒店高档纯棉床单被套枕套 被罩被单1.8米床乔伊斯玫瑰(海蓝色/抗菌)",
"category": "床上用品",
"image": "https://www.shuixing.com/pc/images/2022/logo_02.png",
"price": 899.0
}
},
{
"_index": "shopping",
"_type": "_doc",
"_id": "1001",
"_score": 1.0,
"_source": {
"title": "水星家纺被子夏季空调被 夏凉被夏天被子双人夏被被芯学生宿舍被子200*230cm",
"category": "床上用品",
"image": "https://img11.360buyimg.com/n7/jfs/t1/191056/14/24248/144443/62767f75E23ccafc4/5110691845cfa4cf.jpg",
"price": 139.0
}
}
]
}
}
响应内容里面会包含了是否超时time_out
, 命中:hits
这个里面就是我们查询出来的内容数据了。
