ElasticSearch的常用api

以下操作之前，先看下服务启动情况 http://127.0.0.1:9200/

版本：6.3.1

1、索引操作 操作方式接口参数集群健康GET/_cat/health?v-节点列表GET/_cat/nodes?v-索引列表GET/_cat/indices?v-创建索引PUT/website-查看设置GET/website/_settings-设置索引PUT/website/_settings{"number_of_replicas": "2"}复制索引POST/_reindex{"source":{"index":"website"}, "dest":{"index":"test002"}}关闭索引POST/website/_close-打开索引POST/website/_open-删除索引DELETE/website- 2、文档操作 操作方式接口参数添加文档PUT/website/blog/001{"name": "tom"}获取文档GET/website/blog/001-检查文档是否存在HEAD/website/blog/001-一次取多个POST/website/blog/_mget{"docs": [{"_id": "001"}, {"_id": "002"}] }搜索多个POST/website/_search{"query":{"terms": {"_id":["001", "002"]}}}更新文档(doc方式)POST/website/blog/001/_update{"doc":{"name":"Jack" }}更新文档(脚本方式)POST/website/blog/001/_update{ "script":{"inline": "ctx._source.star += params.star", "lang":"painless","params":{ "star":100} }}查询更新POST/website/_update_by_query{"script":{"inline":"ctx._source.age = 23", "lang":"painless"}, "query":{"term":{"name":"Tom"} } }删除文档（指定ID）DELETE/website/blog/001-删除文档（带查询条件）DELETE/website{"query":{"term":{"name":"Tom"} } }批量操作(多行格式)POST/_bulk{"index":{ "_index": "books", "_type": "IT", "_id": "1" }}{"name": "Tom"} 3、搜索操作

搜索查询 POST | /website/_search

操作参数查看所有{"query":{"match_all":{} } }精确匹配{"query":{"constant_score":{"filter":{"term":{"price":549} } } } }词项查询（term query）{"query":{"term":{"title":"java"} } }分词查询（match query）{"query":{"match":{"title":"Core Java"} } }分词查询（全部匹配）{"query":{"match":{"title":{"query":"Core Java", "operator":"and"} } } }顺序匹配{"query":{"match_phrase":{"title":"Core Java"} } }前缀匹配{"query":{"match_phrase_prefix":{"title":"Core J"} } }多字段搜索{"query":{"multi_match":{"query":"1986 deep", "fields":["title", "description"] } } }多词查询{"query":{"terms":{"title":["deep", "core"] } } }范围查询{"query":{"range":{"publish_time":{"gte":"2016-01-01", "lte":"2016-12-31", "format":"yyyy-MM-dd"} } } }存在字段查询{"query":{"exists":{"field":"author"} } }前缀查询{"query":{"prefix":{"title":"cor"} } }通配符查询（"?“一个，”*"多个）{"query":{"wildcard":{"title":"cor?"} } }正则表达式{"query":{"regexp":{"description":"[0-9]{4}"} } }模糊查询{"query":{"fuzzy":{"description":"1987"} } }复合查询（must， should， must_not， filter）{"query":{"bool":{"must":{"term":{"title":"java"} }, "must_not":[{"term":{"title":"core"}} ] } } }脚本查询{"query":{"bool":{"must":{"script":{"script":{"inline":"doc['price'].value>500", "lang":"painless"} } } } } }指定排序字段{"query":{"term":{"title":"java"} }, "sort":[{"price":{"order":"desc"}} ] } 4、其他操作 操作方式接口参数分词效果POST/website/_analyze{"field":"title", "text":"Core Java", "analyzer": "ik_smart"}设置分词器PUT/blog{"settings" : {"index" : {"analysis.analyzer.default.type": "ik_max_word"} } }分页GET/website/_search?size=10&from=0-高亮POST/website/_search{"query" : {"match_phrase" : {"about" : "rock climbing"} }, "highlight": {"fields" : {"about" : {} } } }数量GET/website/_count-
