1 查看es中有哪些索引
|
GET /_cat/indices?v |
es 中会默认存在一个名为.kibana的索引
表头的含义
|
health |
green(集群完整) yellow(单点正常、集群不完整) red(单点不正常) |
|
status |
是否能使用 |
|
index |
索引名 |
|
uuid |
索引统一编号 |
|
pri |
主节点几个 |
|
rep |
从节点几个 |
|
docs.count |
文档数 |
|
docs.deleted |
文档被删了多少 |
|
store.size |
整体占空间大小 |
|
pri.store.size |
主节点占 |
2 增加一个索引
|
PUT /movie_index |
3 删除一个索引
ES 是不删除也不修改任何数据的，而是增加版本号
|
DELETE /movie_index |
4. 新增文档
1）格式 PUT /index/type/id
|
PUT /movie_index/movie/1 { "id":1, "name":"operation red sea", "doubanScore":8.5, "actorList":[ {"id":1,"name":"zhang yi"}, {"id":2,"name":"hai qing"}, {"id":3,"name":"zhang han yu"} ] } PUT /movie_index/movie/2 { "id":2, "name":"operation meigong river", "doubanScore":8.0, "actorList":[ {"id":3,"name":"zhang han yu"} ] }
PUT /movie_index/movie/3 { "id":3, "name":"incident red sea", "doubanScore":5.0, "actorList":[ {"id":4,"name":"zhang chen"} ] } |
如果之前没建过index或者type，es 会自动创建。
5 直接用id查找
|
GET movie_index/movie/1 |
6 修改—整体替换
|
PUT /movie_index/movie/3 { "id":"3", "name":"incident red sea", "doubanScore":"5.0", "actorList":[ {"id":"1","name":"zhang chen"} ] } |
7 修改—某个字段
|
POST movie_index/movie/3/_update { "doc": { "doubanScore":"7.0" } } |
8 删除一个document
|
DELETE movie_index/movie/3 |
9 搜索type全部数据
|
GET movie_index/movie/_search |
结果
|
{ "took": 2, //耗费时间 毫秒 "timed_out": false, //是否超时 "_shards": { "total": 5, //发送给全部5个分片 "successful": 5, "skipped": 0, "failed": 0 }, "hits": { "total": 3, //命中3条数据 "max_score": 1, //最大评分 "hits": [ // 结果 { "_index": "movie_index", "_type": "movie", "_id": 2, "_score": 1, "_source": { "id": "2", "name": "operation meigong river", "doubanScore": 8.0, "actorList": [ { "id": "1", "name": "zhang han yu" } ] } 。。。。。。。。 。。。。。。。。 } |
10 按条件查询(全部)
|
GET movie_index/movie/_search { "query":{ "match_all": {} } } |
