一、簡單的crud操作
1、添加

|
put /index/type/id{ "json數(shù)據(jù)"} |
2、查詢
|
1
|
get /index/type/id |
3、修改
|

post /index/type/id/_update{ "doc": { "field": "值" }} |
4、刪除
|

delete /index/type/id |
二、搜索
搜索可以分成六大類
- 1、query string search
- 2、query dsl
- 3、query filter

{ "took": 2, "timed_out": false, "_shards": { "total": 5, "successful": 5, "failed": 0 }, "hits": { "total": 3, "max_score": 1, "hits": [ { "_index": "supplier", "_type": "user", "_id": "2", "_score": 1, "_source": { "name": "lisi", "age": 26, "address": "bei jing tong zhou", "price": 10000, "dept": [ "kaifabu" ] } }, { "_index": "supplier", "_type": "user", "_id": "1", "_score": 1, "_source": { "name": "zhangsan", "age": 30, "address": "bei jing chang chun jie", "price": 15000, "dept": [ "kaifabu", "yanfabu" ] } }, { "_index": "supplier", "_type": "user", "_id": "3", "_score": 1, "_source": { "name": "wangwu", "age": 26, "address": "bei jing tong zhou yun he ming zhu", "price": 13000, "dept": [ "kaifabu" ] } } ] }} |
took：耗費了幾毫秒
timed_out：是否超時，這里是沒有
_shards：數(shù)據(jù)拆成了5個分片，所以對于搜索請求，會打到所有的primary shard（或者是它的某個replica shard也可以）
hits.total：查詢結(jié)果的數(shù)量，3個document
hits.max_score：score的含義，就是document對于一個search的相關(guān)度的匹配分數(shù)，越相關(guān)，就越匹配，分數(shù)也高
hits.hits：包含了匹配搜索的document的詳細數(shù)據(jù)
2、query dsl
查詢所有

get supplier/user/_search{ "query": { "match_all": {} }, "_source": ["name", "price"]} |
3、query filter
搜索name為‘lisi'并且price大于1500的

4、full-text search（全文檢索）
address這個字段，會先被拆解，建立倒排索引

|
get /ecommerce/product/_search{ "query" : { "match" : { "address" : "bei jing" } }} |
5、phrase search（短語搜索）
跟全文檢索相對應(yīng)，相反，全文檢索會將輸入的搜索串拆解開來，去倒排索引里面去一一匹配，只要能匹配上任意一個拆解后的單詞，就可以作為結(jié)果返回
phrase search，要求輸入的搜索串，必須在指定的字段文本中，完全包含一模一樣的，才可以算匹配，才能作為結(jié)果返回
