ES中提供了一种强大的检索数据方式,这种检索方式称之为Query DSL（Domain Specified Language）

Query DSL是利用Rest API传递JSON格式的请求体(RequestBody)数据与ES进行交互，这种方式的丰富查询语法让ES检索变得更强大，更简洁

文档： https://www.elastic.co/guide/en/elasticsearch/reference/7.17/query-dsl.html

GET /es_db/_doc/_search {json请求体数据}
OR
GET /es_db/_search {json请求体数据}

demo

get /es_test/_search
{"query": {"match_all": {}},"from": 0,"size": 10000,"sort": [{"_id": "desc"}]}

查询所有match_all

1.查询所有match_all

使用match_all，默认只会返回10条数据。
原因：_search查询默认采用的是分页查询，每页记录数size的默认值为10。如果想显示更多数据，指定size

2.返回指定条数size （默认10，最大(from+size)<=10000）

size 关键字: 指定查询结果中返回指定条数。默认返回值10条

get /es_test/_search
{"query": {"match_all": {}},"from": 2,"size": 10000,"sort": [{"_id": "desc"}]
}
response
{"error" : {"root_cause" : [{"type" : "illegal_argument_exception","reason" : "Result window is too large, from + size must be less than or equal to: [10000] but was [10002].

See the scroll api for a more efficient way to request large data sets. This limit can be set by changing the [index.max_result_window] index level setting."}}},"status" : 400
}

异常原因：
1、查询结果的窗口太大，from + size的结果必须小于或等于10000，而当前查询结果的窗口为20000。
2、可以采用scroll api更高效的请求大量数据集。
3、查询结果的窗口的限制可以通过参数index.max_result_window进行设置。

注意：参数index.max_result_window主要用来限制单次查询满足查询条件的结果窗口的大小，窗口大小由from + size共同决定。不能简单理解成查询返回给调用方的数据量。这样做主要是为了限制内存的消耗。

比如：from为1000000，size为10，逻辑意义是从满足条件的数据中取1000000到（1000000 + 10）的记录。这时ES一定要先将（1000000 + 10）的记录（即result_window）加载到内存中，再进行分页取值的操作。尽管最后我们只取了10条数据返回给客户端，但ES进程执行查询操作的过程中确需要将（1000000 + 10）的记录都加载到内存中，可想而知对内存的消耗有多大。这也是ES中不推荐采用（from + size）方式进行深度分页的原因。

同理，from为0，size为1000000时，ES进程执行查询操作的过程中确需要将1000000 条记录都加载到内存中再返回给调用方，也会对ES内存造成很大压力。

PUT /es_test/_settings
{ "index.max_result_window" :"20000"
}
#修改现有所有的索引，但新增的索引，还是默认的10000
PUT /_all/_settings
{ "index.max_result_window" :"20000"
}#查看所有索引中的index.max_result_window值
GET /_all/_settings/index.max_result_window
{"es_test" : {"settings" : {"index" : {"max_result_window" : "20000"}}},"test" : {"settings" : {"index" : {"max_result_window" : "10000"}}}
}

3.分页查询form

from 关键字: 用来指定起始返回位置，和size关键字连用可实现分页效果

get /es_test/_search
{"from": 2,"size": 10000
}

4.深分页查询Scroll

改动index.max_result_window参数值的大小，只能解决一时的问题，当索引的数据量持续增长时，在查询全量数据时还是会出现问题。而且会增加ES服务器内存大结果集消耗完的风险。最佳实践还是根据异常提示中的采用scroll api更高效的请求大量数据集。

查询命令中新增scroll=1m,说明采用游标查询，保持游标查询窗口一分钟
这里由于测试数据量不够，所以size值设置为2
实际使用中为了减少游标查询的次数，可以将值适当增大，比如设置为1000

查询结果：
除了返回前2条记录，还返回了一个游标ID值_scroll_id

多次根据scroll_id游标查询，直到没有数据返回则结束查询。采用游标查询索引全量数据，更安全高效，限制了单次对内存的消耗。

默认为500 高并发下会报错：
elasticsearch7.x max_open_scroll_context Trying to create too many scroll contexts. Must be less than or equal to 500

GET /es_test/_search?scroll=1m 
{"query": { "match_all": {}},"size":  2

}GET /_search/scroll

}

5.指定字段排序sort

注意：会让得分失效

#排序，分页

GET /es_test/_search
{"query": {"match_all": {}},"sort": [{"age": "desc"}],"from": 10,"size": 5
}

6.返回指定字段_source

_source 关键字: 是一个数组,在数组中用来指定展示那些字段

GET /es_test/_search
{"query": {"match_all": {}},"_source": ["name","address"]
}

默认OR匹配所有match

match 在匹配时会对所查找的关键词进行分词，然后按分词匹配查找

match支持以下参数：

query : 指定匹配的值
operator : 匹配条件类型
- and : 条件分词后都要匹配
- or : 条件分词后有一个匹配即可(默认)
minmum_should_match : 最低匹配度，即条件在倒排索引中最低的匹配度

#模糊匹配 match 分词后or的效果
GET /es_test/_search
{"query": {"match": {"address": "广州白云山公园"}}
}
# 分词后 and的效果
GET /es_test/_search
{"query": {"match": {"address": {"query": "广州白云山公园","operator": "AND"}}}
}

在match中的应用：当operator参数设置为or时，minnum_should_match参数用来控制匹配的分词的最少数量。

# 最少匹配广州，公园两个词
GET /es_test/_search
{"query": {"match": {"address": {"query": "广州公园","minimum_should_match": 2}}}
}

短语查询match_phrase

match_phrase查询分析文本并根据分析的文本创建一个短语查询。match_phrase会将检索关键词分词

match_phrase的分词结果必须在被检索字段的分词中都包含，而且顺序必须相同，而且默认必须都是连续的

GET /es_test/_search
{"query": {"match_phrase": {"address": "广州白云山"}}
}
GET /es_test/_search
{"query": {"match_phrase": {"address": "广州白云"}}
}

思考：为什么查询广州白云山有数据，广州白云没有数据？

分析原因：

先查看广州白云山公园分词结果，可以知道广州和白云不是相邻的词条，中间会隔一个白云山，而match_phrase匹配的是相邻的词条，所以查询广州白云山有结果，但查询广州白云没有结果。

POST _analyze
{"analyzer":"ik_max_word","text":"广州白云山"
}
response
{"tokens" : [{"token" : "广州","start_offset" : 0,"end_offset" : 2,"type" : "CN_WORD","position" : 0},{"token" : "白云山","start_offset" : 2,"end_offset" : 5,"type" : "CN_WORD","position" : 1},{"token" : "白云","start_offset" : 2,"end_offset" : 4,"type" : "CN_WORD","position" : 2},{"token" : "云山","start_offset" : 3,"end_offset" : 5,"type" : "CN_WORD","position" : 3}]
}

如何解决词条间隔的问题？可以借助slop参数，slop参数告诉match_phrase查询词条能够相隔多远时仍然将文档视为匹配

#广州云山分词后相隔为2，可以匹配到结果
GET /es_test/_search
{"query": {"match_phrase": {"address": {"query": "广州云山","slop": 2} }}
}

多字段查询multi_match

可以根据字段类型，决定是否使用分词查询，得分最高的在前面

注意：字段类型分词,将查询条件分词之后进行查询，如果该字段不分词就会将查询条件作为整体进行查询

GET /es_test/_search
{"query": {"multi_match": {"query": "长沙万里","fields": ["address","name"]}}
}

最佳匹配

GET /es_test/_search
{"query": {"multi_match": {"type": "best_fields", //most_fields"query": "长沙万里","fields": ["address","name"]}}
}

query_string (AND | OR | NOT)

允许我们在单个查询字符串中指定AND | OR | NOT条件，同时也和 multi_match query一样，支持多字段搜索。

和match类似，但是match需要指定字段名，query_string是在所有字段中搜索，范围更广泛。

注意: 查询字段分词就将查询条件分词查询，查询字段不分词将查询条件不分词查询

未指定字段查询

GET /es_test/_search
{"query": {"query_string": {"query": "张三 OR 橘子洲"}}
}

指定单个字段查询

#Query String
GET /es_test/_search
{"query": {"query_string": {"default_field": "address","query": "白云山 OR 橘子洲"}}
}

指定多个字段查询

GET /es_test/_search
{"query": {"query_string": {"fields": ["name","address"],"query": "(张三 OR (广州 AND 王五)) NOT 天河"}}
}

simple_query_string

类似Query String，但是会忽略错误的语法,同时只支持部分查询语法，不支持AND OR NOT，会当作字符串处理。支持部分逻辑：

+ 替代AND
| 替代OR
- 替代NOT

simple_query_string 默认的operator是OR

GET /es_test/_search
{"query": {"simple_query_string": {"fields": ["name","address"],"query": "广州公园","default_operator": "AND"}}
}GET /es_test/_search
{"query": {"simple_query_string": {"fields": ["name","address"],"query": "广州 + 公园"}}
}

关键词查询Term

Term用来使用关键词查询(精确匹配),还可以用来查询没有被进行分词的数据类型。Term是表达语意的最小单位，搜索和利用统计语言模型进行自然语言处理都需要处理Term。

match在匹配时会对所查找的关键词进行分词，然后按分词匹配查找，而term会直接对关键词进行查找。

一般模糊查找的时候，多用match，而精确查找时可以使用term。

ES中默认使用分词器为标准分词器(StandardAnalyzer),标准分词器对于英文单词分词,对于中文单字分词。
在ES的Mapping Type 中 keyword , date ,integer, long , double , boolean or ip 这些类型不分词，只有text类型分词。

# 思考： 查询广州白云是否有数据，为什么？
GET /es_test/_search
{"query":{"term": {"address": {"value": "广州白云"}}}
}# 采用term精确查询, 查询字段映射类型为keyword
GET /es_test/_search
{"query":{"term": {"address.keyword": {"value": "广州白云山公园"}}}
}

对于英文，可以考虑建立索引时忽略大小写

在ES中，Term查询，对输入不做分词。会将输入作为一个整体，在倒排索引中查找准确的词项，并且使用相关度算分公式为每个包含该词项的文档进行相关度算分。

PUT /es_good/_bulk
{"index":{"_id":1}}
{"productId":"xxx123","productName":"iPhone"}
{"index":{"_id":2}}
{"productId":"xxx111","productName":"iPad"}# 思考： 查询iPhone可以查到数据吗？  
GET /es_good/_search
{"query":{"term": {"productName": {"value": "iPhone"}}}
}GET /es_good/_analyze
{"analyzer":"standard","text":"iPhone"
}
response
{"tokens" : [{"token" : "iphone","start_offset" : 0,"end_offset" : 6,"type" : "<ALPHANUM>","position" : 0}]
}#1. 使用keyword搜索
get /es_good/_search
{"query": {"term": {"productName.keyword": {"value": "iPhone"}}}
}#2. 对于英文，可以考虑建立索引时忽略大小写
PUT /es_good
{"settings": {"analysis": {"normalizer": {"es_normalizer": {"filter": ["lowercase","asciifolding"],"type": "custom"}}}},"mappings": {"properties": {"productId": {"type": "text"},"productName": {"type": "keyword","normalizer": "es_normalizer","index": "true"}}}
}

Constant Score 避免算分

可以通过 Constant Score 将查询转换成一个 Filtering，避免算分，并利用缓存，提高性能。

将 Query 转成 Filter，忽略TF-IDF计算，避免相关性算分的开销

Filter可以有效利用缓存

GET /es_test/_search
{"query": {"constant_score": {"filter": {"term": {"address.keyword": "广州白云山公园"}}}}
}

ES中的结构化搜索

结构化搜索(Structured search)是指对结构化数据的搜索。

结构化数据：

日期，布尔类型和数字都是结构化的
文本也可以是结构化的。
如彩色笔可以有离散的颜色集合：红(red) 、绿(green、蓝(blue)
一个博客可能被标记了标签，例如，分布式(distributed)和搜索(search)
电商网站上的商品都有UPC(通用产品码Universal Product Code)或其他的唯一标识，它们都需要遵从严格规定的、结构化的格式。

应用场景：对bool，日期，数字，结构化的文本可以利用term做精确匹配

GET /es_test/_search
{"query": {"term": {"age": {"value": 28}}}
}

term处理多值字段，term查询是包含，不是等于

POST /es_employee/_bulk
{"index":{"_id":1}}
{"name":"小明","interest":["跑步","篮球"]}
{"index":{"_id":2}}
{"name":"小红","interest":["跳舞","画画"]}
{"index":{"_id":3}}
{"name":"小丽","interest":["跳舞","唱歌","跑步"]}POST /es_employee/_search
{"query": {"term": {"interest.keyword": {"value": "跑步"}}}
}

前缀查询prefix

它会对分词后的term进行前缀搜索。

它不会分析要搜索字符串，传入的前缀就是想要查找的前缀

默认状态下，前缀查询不做相关度分数计算，它只是将所有匹配的文档返回，然后赋予所有相关分数值为1。它的行为更像是一个过滤器而不是查询。两者实际的区别就是过滤器是可以被缓存的，而前缀查询不行

prefix的原理：需要遍历所有倒排索引，并比较每个term是否已所指定的前缀开头

过程：所有倒排索引广州都查出来

GET /es_test/_search
{"query": {"prefix": {"address": {"value": "广州"}}}
}

通配符查询wildcard

通配符查询：工作原理和prefix相同，只不过它不是只比较开头，它能支持更为复杂的匹配模式。

GET /es_test/_search
{"query": {"wildcard": {"address": {"value": "*白*"}}}
}

范围查询range

range：范围关键字
gte 大于等于
lte 小于等于
gt 大于
lt 小于
now 当前时间

POST /es_db/_search
{"query": {"range": {"age": {"gte": 25,"lte": 28}}}
}

日期range

DELETE /es_good
POST /es_good/_bulk
{"index":{"_id":1}}
{"price":100,"date":"2021-01-01","productId":"XHDK-1293"}
{"index":{"_id":2}}
{"price":200,"date":"2022-01-01","productId":"KDKE-5421"}GET /es_good/_mappingGET /es_good/_search
{"query": {"range": {"date": {"gte": "now-2y"}}}
}

多id查询ids

ids 关键字: 值为数组类型,用来根据一组id获取多个对应的文档

GET /es_test/_search
{"query": {"ids": {"values": [1,2]}}
}

或者批量查询

GET /es_test/_mget
{"ids": [1,2]
}

模糊查询fuzzy

在实际的搜索中，我们有时候会打错字，从而导致搜索不到。在Elasticsearch中，我们可以使用fuzziness属性来进行模糊查询，从而达到搜索有错别字的情形。

fuzzy 查询会用到两个很重要的参数，fuzziness，prefix_length

fuzziness：表示输入的关键字通过几次操作可以转变成为ES库里面的对应field的字段

操作是指：新增一个字符，删除一个字符，修改一个字符，每次操作可以记做编辑距离为1，
如中文集团到中威集团编辑距离就是1，只需要修改一个字符；
该参数默认值为0，即不开启模糊查询。
如果fuzziness值在这里设置成2，会把编辑距离为2的东东集团也查出来。

prefix_length：表示限制输入关键字和ES对应查询field的内容开头的第n个字符必须完全匹配，不允许错别字匹配

如这里等于1，则表示开头的字必须匹配，不匹配则不返回
默认值也是0
加大prefix_length的值可以提高效率和准确率。

注意: fuzzy 模糊查询最大模糊错误必须在0-2之间
搜索关键词长度为 2，不允许存在模糊
搜索关键词长度为3-5，允许1次模糊
搜索关键词长度大于5，允许最大2次模糊

GET /es_test/_search
{"query": {"fuzzy": {"address": {"value": "白运山","fuzziness": 1    }}}
}GET /es_test/_search
{"query": {"match": {"address": {"query": "广洲","fuzziness": 1}}}
}

高亮highlight

highlight 关键字: 可以让符合条件的文档中的关键词高亮。

highlight相关属性：

pre_tags 前缀标签
post_tags 后缀标签
tags_schema 设置为styled可以使用内置高亮样式
require_field_match 多字段高亮需要设置为false
