常用命令請(qǐng)求
- 獲取健康狀況
GET /_cat/health?v

- 創(chuàng)建名字為customer的索引
PUT /customer?pretty
- 給customer索引存入數(shù)據(jù)
PUT /customer/doc/1?pretty
{
"name": "John Doe"
}
Elasticsearch并不要求你在索引文檔之前先顯性的創(chuàng)建索引。在4硅堆、5步驟中宛瞄，如果在執(zhí)行步驟5時(shí)，customer索引還沒(méi)有創(chuàng)建，Elasticsearch將會(huì)自動(dòng)的創(chuàng)建這個(gè)索引
- 刪除索引
DELETE /customer?pretty
訪問(wèn)數(shù)據(jù)命令模板為：<REST Verb> /<Index>/<Type>/<ID>
- 修改數(shù)據(jù)
PUT /customer/doc/1?pretty
{
"name": "Jane Doe"
}
- 非顯性的指定id科盛，elasticsearch會(huì)自動(dòng)創(chuàng)建
POST /customer/doc?pretty
{
"name": "Jane Doe"
}
- 更新文檔
POST /customer/doc/1/_update?pretty
{
"doc": { "name": "Jane Doe" }
}
- 更新并添加數(shù)據(jù)
POST /customer/doc/1/_update?pretty
{
"doc": { "name": "Jane Doe", "age": 20 }
}
- 刪除文檔
DELETE /customer/doc/2?pretty
- 批量操作妇多，使用_bulk
- 索引兩個(gè)文檔
POST /customer/doc/_bulk?pretty
{"index":{"_id":"1"}}
{"name": "John Doe" }
{"index":{"_id":"2"}}
{"name": "Jane Doe" }
- 更新id=1的文檔，刪除id=2的文檔
POST /customer/doc/_bulk?pretty
{"update":{"_id":"1"}}
{"doc": { "name": "John Doe becomes Jane Doe" } }
{"delete":{"_id":"2"}}
- 搜索洼专，通過(guò)_search
- 通過(guò)請(qǐng)求URL
GET /bank/_search?q=*&sort=account_number:asc&pretty //返回bank索引的所有文檔
- q=* 匹配bank索引中的所有文檔
- sort=account_number:asc 使用每個(gè)文檔中的account_number字段進(jìn)行升序排序
- pretty 告訴Elasticsearch返回 pretty-printed JSON 結(jié)果
- 通過(guò)請(qǐng)求體
GET /bank/_search
{
"query": { "match_all": {} },
"sort": [
{ "account_number": "asc" }
]
}

- took Elasticsearch查詢耗費(fèi)時(shí)間棒掠，單位毫秒
- timed_out 查詢是否超時(shí)
- _shards 查詢了多少個(gè)分片，和查詢成功/跳過(guò)/失敗的分片的數(shù)量
- hits 查詢結(jié)果
- hits.total 匹配搜索條件的所有文檔數(shù)
- hits.hits 搜索結(jié)果的實(shí)際數(shù)組（默認(rèn)前10個(gè)文檔）
- hits.sort 結(jié)果排序的key
- hits._score 和 max_score 現(xiàn)在可以忽略的字段
