Elasticsearch常用操作API
1. 查询所有的索引# curl '10.0.0.5:9200/_cat/indices?v'
health status index pri rep docs.count docs.deleted store.size pri.store.size
yellow open customer 5 1 2 0 6.6kb 6.6kb
yellow open bank 5 1 1000 0 442.1kb 442.1kb
2. 查询bank表中的所有数据
# curl '10.0.0.5:9200/bank/_search?q=*&pretty'

[*] took –Elasticsearch执行查询的毫秒响应时间
[*] timed_out – 是否超时
[*] _shards – 查询过的分片，包含成功的分片和失败的分片
[*] hits – 搜索结果
[*] hits.total – 符合搜索结果的记录数
[*] hits.hits – 默认显示前10条搜索结果
[*] _score and max_score - ignore these fields for now
3. 另外一种查询全部结果的方法
curl -XPOST '10.0.0.5:9200/bank/_search?pretty' -d '
{
"query": { "match_all": {} }
}'
4. 分页排序的检索例子
# curl -XPOST '10.0.0.5:9200/bank/_search?pretty' -d '
{
"query": { "match_all": {} },
"from": 10,
"size": 3,
"sort": { "balance": { "order": "desc" } }
}'
{
"took" : 8,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 1000,
"max_score" : null,
"hits" : [ {
"_index" : "bank",
"_type" : "account",
"_id" : "255",
"_score" : null,
"_source" : {
"account_number" : 255,
"balance" : 49339,
"firstname" : "Iva",
"lastname" : "Rivers",
"age" : 38,
"gender" : "M",
"address" : "470 Rost Place",
"employer" : "Mantrix",
"email" : "ivarivers@mantrix.com",
"city" : "Disautel",
"state" : "MD"
},
"sort" : [ 49339 ]
}, {
"_index" : "bank",
"_type" : "account",
"_id" : "524",
"_score" : null,
"_source" : {
"account_number" : 524,
"balance" : 49334,
"firstname" : "Salas",
"lastname" : "Farley",
"age" : 30,
"gender" : "F",
"address" : "499 Trucklemans Lane",
"employer" : "Xumonk",
"email" : "salasfarley@xumonk.com",
"city" : "Noxen",
"state" : "AL"
},
"sort" : [ 49334 ]
}, {
"_index" : "bank",
"_type" : "account",
"_id" : "751",
"_score" : null,
"_source" : {
"account_number" : 751,
"balance" : 49252,
"firstname" : "Patrick",
"lastname" : "Osborne",
"age" : 23,
"gender" : "M",
"address" : "915 Prospect Avenue",
"employer" : "Gynko",
"email" : "patrickosborne@gynko.com",
"city" : "Takilma",
"state" : "MO"
},
"sort" : [ 49252 ]
} ]
}
}
5. 添加文档，如果id存在则更新文档
# curl -XPUT '10.0.0.5:9200/customer/external/1?pretty' -d '
> {"name":"John Doe"}'
{
"_index" : "customer",
"_type" : "external",
"_id" : "1",
"_version" : 1,
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"created" : true
}
# curl -XPUT '10.0.0.5:9200/customer/external/1?pretty' -d '
{"name":"Jane Doe"}'
{
"_index" : "customer",
"_type" : "external",
"_id" : "1",
"_version" : 2,
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"created" : false
}
6. 不指定Id时创建文档，可以发现自动生成一个随机Id
# curl -XPOST '10.0.0.5:9200/customer/external?pretty' -d '{"name": "Jane Doe"}'
{
"_index" : "customer",
"_type" : "external",
"_id" : "AVTh53KZ4Pj5B2ZQ2voK",
"_version" : 1,
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"created" : true
}
7. 修改文档
# curl -XPOST '10.0.0.5:9200/customer/external/2/_update?pretty' -d '{"doc":{"name":"favourite boy","age":18}}'
{
"_index" : "customer",
"_type" : "external",
"_id" : "2",
"_version" : 3,
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
}
}
8. 在开启javascript后，可以使用JS脚本更新文档
# curl -XPOST '10.0.0.5:9200/customer/external/2/_update?pretty' -d '{"script":"ctx._source.age+=5"}'
9. 删除文档
# curl -XDELETE '10.0.0.5:9200/customer/external/1?pretty'
{
"found" : true,
"_index" : "customer",
"_type" : "external",
"_id" : "1",
"_version" : 4,
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
}
}
10. 批量更新文档
# curl -XPOST '10.0.0.5:9200/customer/external/_bulk?pretty' -d '
{"index":{"_id":"1"}}
{"name": "John Doe" }
{"index":{"_id":"2"}}
{"name": "Jane Doe" }'
{
"took" : 33,
"errors" : false,
"items" : [ {
"index" : {
"_index" : "customer",
"_type" : "external",
"_id" : "1",
"_version" : 3,
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"status" : 200
}
} ]
}
# curl -XPOST '10.0.0.5:9200/customer/external/_bulk?pretty' -d '
> {"update":{"_id":"1"}}
> {"doc": { "name": "John Doe becomes Jane Doe" } }
> {"delete":{"_id":"2"}}
> '
{
"took" : 34,
"errors" : false,
"items" : [ {
"update" : {
"_index" : "customer",
"_type" : "external",
"_id" : "1",
"_version" : 4,
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"status" : 200
}
}, {
"delete" : {
"_index" : "customer",
"_type" : "external",
"_id" : "2",
"_version" : 5,
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"status" : 200,
"found" : true
}
} ]
