写入 doc
put product/_doc/1
{
"name": "apple",
"price": 5.6
}
返回
{
"_index": "product",
"_id": "1",
"_version": 3,
"result": "updated",
"_shards": {
"total": 2,
"successful": 1,
"failed": 0
},
"_seq_no": 2,
"_primary_term": 1
}
查询 doc
get /product/_doc/1
返回
{
"_index": "product",
"_id": "1",
"_version": 3,
"_seq_no": 2,
"_primary_term": 1,
"found": true,
"_source": {
"name": "apple",
"price": 5.6
}
}
查看所有 index
get _cat/indices
从 index 中 from 第几个数据开始,size 个docs
GET kibana_sample_data_logs/_search?from=1&size=2
创建 index
PUT test_index
{
"settings":{
"number_of_shards": 1,
"number_of_replicas": 1
}
}
删除 index
DELETE test_index
创建完 index 后,主分片数量、index名、字段类型
不可以再修改
重新创建文档,只会带过来 doc,属性设置不会带过来
POST _reindex
{
"source": {
"index": "test_index"
},
"dest": {
"index": "new_test_index"
}
}
检查 index 是否存在
head new_test_index
创建发生在 主分片(可读可写) 操作类型:
PUT test_index/_doc/1?op_type=create
{
"name": "test1"
}
id 1 的 doc 已存在,create 报错
{
"error": {
"root_cause": [
{
"type": "version_conflict_engine_exception",
"reason": "[1]: version conflict, document already exists (current version [1])",
"index_uuid": "ntM1X5SOTxiz8tRVwdHK6g",
"shard": "0",
"index": "test_index"
}
],
"type": "version_conflict_engine_exception",
"reason": "[1]: version conflict, document already exists (current version [1])",
"index_uuid": "ntM1X5SOTxiz8tRVwdHK6g",
"shard": "0",
"index": "test_index"
},
"status": 409
}
index 操作,替换 doc
PUT test_index/_doc/1?op_type=index
{
"name": "test_new"
}
{
"_index": "test_index",
"_id": "1",
"_version": 2,
"result": "updated",
"_shards": {
"total": 2,
"successful": 1,
"failed": 0
},
"_seq_no": 1,
"_primary_term": 1
}
POST 可以自动生成 随机 id
POST test_index/_doc/
{
"name": "test_new"
}
{
"_index": "test_index",
"_id": "YrdpU4UBIo5EnYllVY0M",
"_version": 1,
"result": "created",
"_shards": {
"total": 2,

"failed": 0
},
"_seq_no": 4,
"_primary_term": 1
}
