Elasticsearch(三) 使用kibana 操作ES

文档中包含语句

1，索引（新增查询删除）
2, mapping 创建
3，文档（新增，修改，删除，批量新增）
4，文档查询（基本查询，高级查询，分页，高亮，排序）

1,使用kibana 新增查询删除索引：

新增请求：
PUT /goodsindex返回：
{"acknowledged" : true,"shards_acknowledged" : true,"index" : "goodsindex"
}

查询请求：
GET /goodsindex
返回：
{"goodsindex" : {"aliases" : { },"mappings" : { },"settings" : {"index" : {"creation_date" : "1590992920969","number_of_shards" : "5","number_of_replicas" : "1","uuid" : "FHD9se3qSY-0XOD2t6HprQ","version" : {"created" : "6080099"},"provided_name" : "goodsindex"}}}
}

删除请求：
DELETE /goodsindex
返回:
{"acknowledged" : true
}

2,新增mapping映射

//先创建索引
PUT /xiaohui
//创建mapping
PUT /xiaohui/_mapping/goods   //或 PUT /xiaohui/goods/_mapping
{ "properties": {"title":{"type":"text","analyzer":"ik_max_word"},"subtilte":{"type":"text","analyzer":"ik_max_word"},"images":{"type":"keyword","index":"false"//表示不分词},"price":{"type":"float"}}
}

一次性创建索引以及mapping映射：

PUT /xiaohui2
{"settings": {},"mappings": {"goods": {"properties": {"title": {"type": "text","analyzer": "ik_max_word"},"subtilte": {"type": "text","analyzer": "ik_max_word"},"images": {"type": "keyword","index": "false"},"price": {"type": "float"}}}}

其中字段中的属性相关解释如下：

store:是否独立存储，默认数据都存储在_source下，个别独立出来的查询效率较高，默认false

3,文档操作

添加文档：

方式一：自动生成主键id:
POST /xiaohui/goods
{"title":"小米手机","subtilte":"手机描述","images":"http://www.shouji.com/sss.jpg","price":2342
}

方式二 指定id
POST /xiaohui/goods/1001
{"title":"小米手机2","subtilte":"手机描述","images":"http://www.shouji.com/sss.jpg","price":2342
}

文档查询：get /xiaohui/goods/1001

修改文档：

PUT /xiaohui/goods/1001
{"title":"红米手机2","subtilte":"手机描述","images":"http://www.shouji.com/sss.jpg","price":2342
}

删除文档:

删除1 根据id删除
DELETE /xiaohui/goods/1001

//删除2 根据查询条件删除
POST /xiaohui/_delete_by_query
{"query":{"match":{"title":"红米手机"}}
}

删除3 全部删除：
POST /xiaohui/_delete_by_query
{"query":{"match_all":{}}
}

批量新增（部分kibana版本可能不支持，不能进行格式化后执行）

POST /xiaohui/goods/_bulk
{"index":{}}{"title":"大米手机","images":"http://www.baidu.com/jjj.jpg","price":21222}
{"index":{}}{"title":"小米手机","images":"http://www.baidu.com/jjj.jpg","price":21222}
{"index":{}}{"title":"小米手机4A","images":"http://www.baidu.com/jjj.jpg","price":21222}

4，文档查询：

1，查询全部

POST /xiaohui/_search
{"query": {"match_all": {}}
}

2，部分关键词查询

POST /xiaohui/_search
{"query": {"match": {"title": "小米电视4A"}}
}

查询指定operator

operator：and 分词后都必须包含，or 包含其一就可以。

POST /xiaohui/_search
{"query": {"match": {"title":{"query":"小米手机4A","operator":"and"} }}
}

多字段查询：

POST /xiaohui/_search
{"query":{"multi_match": {"query": "小米","fields": ["title","subtilte"]}}
}

精确查询 term (可查询那些数字日期布尔值以及未分词的字符串)

POST /xiaohui/_search
{"query":{"term": {"price": {"value": "5999"}}}
}

同一字段两个值精确查询

POST /xiaohui/_search
{"query":{"terms": {"price": ["5999","21222"]}}
}

只返回需要的字段（左右等同）

POST /xiaohui/_search

{

"_source": ["title","price"],

"query":{

"terms": {

"price": ["5999"]

}

POST /xiaohui/_search

{

"_source": {

"includes":["title","price"]

"query":{

"terms": {

"price": ["5999"]

}

剔除不需要的字段

POST /xiaohui/_search
{"_source": {"excludes":["title"]}, "query":{"terms": {"price": ["5999"]}}
}

高级查询：

布尔组合bool

POST /xiaohui/_search
{"query":{"bool":{"must":{"match":{"title":"小米"}},"must_not":{"match":{"title":"4A"}},"should":{"match":{"subtitle":"华为"}}}}
}

范围查询（range）：gt 大于 gte 大于等于 lt小于 lte小于等于

POST /xiaohui/_search
{"query":{"range": {"price": {"gte": 1000,"lte": 6000}}}
}

模糊查询(fuzzy):

POST /xiaohui/_search
{"query":{"fuzzy": {"title":{"value": "app22","fuzziness":2 //容错个数}}}
}

排序(soft)

单字段排序
POST /xiaohui/_search
{"query":{"match_all": {}},"sort": [{"price": {"order": "desc"}}]
}

多字段排序：
POST /xiaohui/_search
{"query":{"match":{"title":"小米"}},"sort": [{"_score": {"order": "desc"}},{"price": {"order": "desc"}} ]
}

高亮展示(highlight)

POST /xiaohui/_search
{"query":{"match":{"title": "小米"}},"highlight": {"pre_tags": "<front color='red'>","post_tags": "</front>","fields": {"title": {}}}
}

分页(from size)

POST /xiaohui/_search
{"query":{"match_all": {}},"from": 0,"size": 2
}
