ES（elasticSearch学习笔记）

什么是es

es是面向文档型的数据库，一条数据在es数据库就是一个文档，和关系型数据库做一个类比：
1：es的索引类比关系型数据库的数据库，
2：es的type类比数据表（7.0版本以上删除了type这个概念），
3：es的索引下的文档document类比关系型数据库的行，新增时可以指定文档主键id,不指定会自动生成
4：es的文档中的字段类比关系关系型数据库的列。

现实生产中一般一个索引类似张表，但是一个索引下的字段还可以是一个对象,可以嵌套。
match每一次全文搜索分词是针对某一个字段的，可以是嵌套搜索，一次全文搜索不是针对整个索引的全部字段，想要同时全文搜多个字段可以一次请求中match多个字段

put请求新建索引，post/put请求新增数据，新增的数据就是一个文档，新增会有一个文档id就是索引下一个数据的主键

涉及的操作索引的增删改查和文档的增删改查

什么是倒排索引

es基本入门操作

1.安装访问
在本地es执行目录：/Users/liuqinhua/Desktop/错误/elasticsearch-7.6.2/bin
执行可执行文件：./elasticsearch
访问

2.创建索引put请求http://localhost:9200/liuqinhua（liuqinhua是索引名）

3**.get请求查看索引信息**：http://localhost:9200/索引名
例如：http://localhost:9200/liuqinhua

4.get请求查看所有的索引:http://localhost:9200/_cat/indices?v
这时候他是强制返回的内容是text格式的，所以会展示成表格的格式

5.delete请求删除索引wudonghui：http://localhost:9200/索引名
例如：http://localhost:9200/wudonghui

6.post请求给索引新增文档数据http://localhost:9200/索引名字/_doc
eg：http://localhost:9200/liuqinhua/_doc
这种会返回文档id
或者post或者put请求：http://localhost:9200/liuqinhua/_doc/自定义文档id

7.get请求查询索引的数据
查询某一个文档id内容
http://localhost:9200/索引名/_doc/文档id
例如：http://localhost:9200/liuqinhua/_doc/1001

get请求查询某一个索引下所有的文档
http://localhost:9200/索引名/_search
例如：
http://localhost:9200/liuqinhua/_search

put请求根据索引下的主键id全量修改更新某一条文档数据

格式：http://localhost:9200/索引名/_doc/数据主键id
eg:http://localhost:9200/liuqinhua/_doc/1001

put全量会把该主键id的文档数据变成这一次传入的

再更新一下：

post请求局部更新某索引下某主键文档id数据
http://localhost:9200/索引名/_update/文档主键id
eg:http://localhost:9200/liuqinhua/_update/1001

delete请求删除索引下某主键的文档
格式http://localhost:9200/索引名/_doc/文档主键id

条件查询

url拼接查询条件
格式：http://localhost:9200/liuqinhua/_search?q=文档下一级key :文档下一级value
二级的key-value是搜不出来的

查询条件放requestbody进行查询放入query-match里面

放requestbody全量查询索引下文档

分页查询

get请求http://localhost:9200/索引名/_search加reqbody里面的多条件查询和范围查询

reqbody内容

{"query":{"bool":{"should":[// must相当于mysql的and,should相当于or{"match":{"uname" :"forbidden"//"gender":26}},{"match":{//"uname" :"forbidden""gender":26}}],"filter":{//过滤"range":{//范围查询"gender":{"gt":26//gt表示大于，gender大于26岁的}}}}}
}

查出结果

{"took": 23,"timed_out": false,"_shards": {"total": 1,"successful": 1,"skipped": 0,"failed": 0},"hits": {"total": {"value": 4,"relation": "eq"},"max_score": 1.4769237,"hits": [{"_index": "user","_type": "_doc","_id": "-rD414IBzFC3z-tJgVq3","_score": 1.4769237,"_source": {"schoolId": "2000014495","teacherUid": "100000094198","uname": "forbidden zhang","unamePing": "forbiddenzhang","gender": 28}},{"_index": "user","_type": "_doc","_id": "-7D414IBzFC3z-tJ2Fqf","_score": 1.4769237,"_source": {"schoolId": "2000014485","teacherUid": "100000094198","uname": "forbidden city","unamePing": "forbiddencity","gender": 30}},{"_index": "user","_type": "_doc","_id": "_LD714IBzFC3z-tJBFra","_score": 1.4769237,"_source": {"schoolId": "2000014485","teacherUid": "100000094198","uname": "forbidden city","unamePing": "forbiddencity","gender": 30}},{"_index": "user","_type": "_doc","_id": "_bAC2IIBzFC3z-tJB1qB","_score": 0.0,"_source": {"schoolId": "2000014485","teacherUid": "100000094199","uname": "sijiali","unamePing": "sijiali","gender": 30}}]}
}

全文检索和完全匹配

url同上,全文检索的核心就是分词后用了倒排，，中文一个字会分做一个词，英文字母是以空格结束当做是一个单词做分词,连续没有空格的n个数字不会分成多个词

reqbody内容：”forbidden 小“把这两个字分词把还有forbidden 和小都查了出来

{"query":{"bool":{"must":[// must相当于mysql的and,should相当于or{"match":{"uname" :"sijiali 华"//"gender":26}},{"match":{"unamePing" :"sijiali liu"//"gender":26}}]}}
}

{"took": 146,"timed_out": false,"_shards": {"total": 1,"successful": 1,"skipped": 0,"failed": 0},"hits": {"total": {"value": 9,"relation": "eq"},"max_score": 4.4716845,"hits": [{"_index": "user","_type": "_doc","_id": "A7BM2IIBzFC3z-tJ01ts","_score": 4.4716845,"_source": {"schoolId": "2000014485","teacherUid": "100000094119","uname": "小华","unamePing": "sijiali liu","gender": 31}},{"_index": "user","_type": "_doc","_id": "ArBI2IIBzFC3z-tJuVt_","_score": 3.5823827,"_source": {"schoolId": "2000014485","teacherUid": "100000094119","uname": "a sijiali 100","unamePing": "sijiali liu","gender": 31}},{"_index": "user","_type": "_doc","_id": "BbBP2IIBzFC3z-tJA1sN","_score": 3.3120766,"_source": {"schoolId": "2000014485","teacherUid": "100000094119","uname": "小华","unamePing": "xiao liu hua","gender": 31}},{"_index": "user","_type": "_doc","_id": "BLBM2IIBzFC3z-tJ41s_","_score": 3.2610822,"_source": {"schoolId": "2000014485","teacherUid": "100000094119","uname": "小华","unamePing": "sijiali ","gender": 31}},{"_index": "user","_type": "_doc","_id": "_bAC2IIBzFC3z-tJB1qB","_score": 2.917797,"_source": {"schoolId": "2000014485","teacherUid": "100000094199","uname": "sijiali","unamePing": "sijiali","gender": 30}},{"_index": "user","_type": "_doc","_id": "_rAv2IIBzFC3z-tJrFrx","_score": 2.3717804,"_source": {"schoolId": "2000014485","teacherUid": "100000094199","uname": "a sijiali b","unamePing": "sijiali","gender": 30}},{"_index": "user","_type": "_doc","_id": "_7A12IIBzFC3z-tJBlrv","_score": 2.3717804,"_source": {"schoolId": "2000014485","teacherUid": "100000094119","uname": "a sijiali 9","unamePing": "sijiali","gender": 30}},{"_index": "user","_type": "_doc","_id": "ALA32IIBzFC3z-tJa1vV","_score": 2.3717804,"_source": {"schoolId": "2000014485","teacherUid": "100000094119","uname": "a sijiali 99","unamePing": "sijiali","gender": 30}},{"_index": "user","_type": "_doc","_id": "AbBE2IIBzFC3z-tJEFt2","_score": 2.3717804,"_source": {"schoolId": "2000014485","teacherUid": "100000094119","uname": "a sijiali 100","unamePing": "sijiali","gender": 31}}]}
}

完全匹配：把match改为match_phrase，相当于mysql的like “%str%”

{"query":{"bool":{"must":[// must相当于mysql的and,should相当于or{"match_phrase":{"uname" :"sijiali"//"gender":26}}]}}
}

{"took": 2,"timed_out": false,"_shards": {"total": 1,"successful": 1,"skipped": 0,"failed": 0},"hits": {"total": {"value": 2,"relation": "eq"},"max_score": 2.581265,"hits": [{"_index": "user","_type": "_doc","_id": "_bAC2IIBzFC3z-tJB1qB","_score": 2.581265,"_source": {"schoolId": "2000014485","teacherUid": "100000094199","uname": "sijiali","unamePing": "sijiali","gender": 30}},{"_index": "user","_type": "_doc","_id": "_rAv2IIBzFC3z-tJrFrx","_score": 1.7744548,"_source": {"schoolId": "2000014485","teacherUid": "100000094199","uname": "a sijiali b","unamePing": "sijiali","gender": 30}}]}
}

分词中文和数字会分作两个词，字母和数字不会分做两个词

中文和数字

{"query":{"bool":{"must":[// must相当于mysql的and,should相当于or{"match":{"uname" :"小9"//"gender":26}}]}}
}返回{"took": 925,"timed_out": false,"_shards": {"total": 1,"successful": 1,"skipped": 0,"failed": 0},"hits": {"total": {"value": 4,"relation": "eq"},"max_score": 2.2984395,"hits": [{"_index": "user","_type": "_doc","_id": "_7A12IIBzFC3z-tJBlrv","_score": 2.2984395,"_source": {"schoolId": "2000014485","teacherUid": "100000094119","uname": "a sijiali 9","unamePing": "sijiali","gender": 30}},{"_index": "user","_type": "_doc","_id": "8bDn14IBzFC3z-tJ1lov","_score": 1.5314121,"_source": {"schoolId": "2000014494","teacherUid": "100000094187","uname": "刘小君","unamePing": "lingweijun01","gender": 23}},{"_index": "user","_type": "_doc","_id": "8LDm14IBzFC3z-tJDVor","_score": 1.5314121,"_source": {"schoolId": "2000014494","teacherUid": "100000094186","uname": "凌小君","unamePing": "lingweijun01","gender": 23}},{"_index": "user","_type": "_doc","_id": "77Dl14IBzFC3z-tJ2FrK","_score": 1.5314121,"_source": {"schoolId": "2000014494","teacherUid": "100000094185","uname": "凌小军","unamePing": "lingweijun01","gender": 23}}]}
}

英文和数字

{"query":{"bool":{"must":[// must相当于mysql的and,should相当于or{"match":{"uname" :"a99"//"gender":26}}]}}
}返回
{"took": 1,"timed_out": false,"_shards": {"total": 1,"successful": 1,"skipped": 0,"failed": 0},"hits": {"total": {"value": 0,"relation": "eq"},"max_score": null,"hits": []}
}

聚合查询

聚合查询相当于mysql的group by

{"aggs":{//定义聚合"fenzu":{//年龄进行分组，给聚合起个名字"terms":{//聚合的类型是 term"field":"gender"//参与聚合的字段"size": 10 // 希望获取的聚合结果数量}}},"size":0//表示不返回文档数组列表0条,设置size为0，结果中不包含文档，只包含聚合结果
}返回{"took": 25,"timed_out": false,"_shards": {"total": 1,"successful": 1,"skipped": 0,"failed": 0},"hits": {"total": {"value": 21,"relation": "eq"},"max_score": null,"hits": []},"aggregations": {"fenzu": {"doc_count_error_upper_bound": 0,"sum_other_doc_count": 0,"buckets": [{"key": 30,"doc_count": 6},{"key": 23,"doc_count": 5},{"key": 26,"doc_count": 4},{"key": 25,"doc_count": 2},{"key": 24,"doc_count": 1},{"key": 28,"doc_count": 1},{"key": 31,"doc_count": 1}]}}
}

映射关系

映射类似关系型数据库中的schema，描述了文档中有哪些字段和字段的类型，如string，data，int等。而类型是一组具有相关性的映射组成，然后使用"properties"来表示该类型中可能包含的字段属性。如果不设置，创建文档的时候会根据每个字段值自动匹配映射关系

可以通过mapping字段修改索引的映射关系

例如


put    http://ip:9200/index_name{"mappings": {"properties": {"realname": {"type": "text","index": true},"username": {"type": "keyword","index": false}}}
}text: 大的长文本，需要做分词，做倒排索引keyword： 不会被分词，也不会被做倒排索引。做精确匹配的搜索（比如订单状态，用的微信号，qq号，手机号）text , keyword 都是属于string类型。

ES 内置分词器

standard：默认分词，单词会被拆分，大小会转换为小写。
simple：按照非字母分词。大写转为小写。
whitespace：按照空格分词。忽略大小写。 s
top：去除无意义单词，比如 the / a / an / is …
keyword：不做分词。把整个文本作为一个单独的关键词

索引下字段的子字段类型，这种情况相当于是一个字段是一个对象的json字符串，但是索引的一级字段没下一层级字段，会有一个默认字段keyword

PUT index_name
{"mappings": {"properties": {"title": {               # 字段名称"type": "text",        # 字段类型"analyzer": "english", # 字段分词器"fields": {            # 多字段域，固定写法"std1": {             # 子字段名称"type": "text",    # 子字段类型"analyzer": "standard"  # 子字段分词器},"ziziduan":{"type": "text",    # 子字段类型"analyzer": "standard"  # 子字段分词器}}}}}
}

es嵌套字段是一个对象，第一层字段直接match搜不出来

content是一个对象，不是一个字符串
索引全部文档内容：

content是一个对象，不是一个字符串，直接match查嵌套字段里面内容查不出来，是一个字符串就可以，：

term查询完全匹配

进一步优化查询，因为是精准查询，不需要查询进行评分计算，只希望对文档进行包括或排除的计算，所以我们会使用 constant_score 查询以非评分模式来执行 term 查询并以一作为统一评分。推荐如下查询
