Elasticsearch需要先安装JDK并配置环境变量，之后下载安装Elasticsearch
启动 ElasticSearch
E:\elasticsearch-7.5.0-windows-x86_64\elasticsearch-7.5.0\bin>elasticsearch.bat
启动成功
启动成功后浏览器地址栏输入：http://localhost:9200/
创建索引
curl -H "Content-Type: application/json" -XPUT "http://localhost:9200/movies/movie/1" -d "{\"title\": \"The Godfather\",\"director\":\"Francis Ford Coppola\",\"year\": 1972}" {"_index":"movies","_type":"movie","_id":"1","_version":3,"result":"updated","_shards":{"total":2,"successful":1,"failed":0},"_seq_no":2,"_primary_term":1}
注意，{}内的双引号记得加反斜杠\转义
由ID获取文档/索引
curl -H "Content-Type: application/json" -XGET "http://localhost:9200/movies/movie/1" -d'' {"_index":"movies","_type":"movie","_id":"1","_version":6,"_seq_no":5,"_primary_term":1,"found":true,"_source":{"title": "The Godfather","director":"Francis Ford Coppola","year": 1972}}
删除文档
curl -H "Content-Type: application/json" -XGET "http://localhost:9200/movies/movie/1" -d'' {"_index":"movies","_type":"movie","_id":"1","found":false}
搜索所有索引和类型 _search
curl -H "Content-Type: application/json" -XGET "http://localhost:9200/_search" {"took":1,"timed_out":false,"_shards":{"total":3,"successful":3,"skipped":0,"failed":0},"hits":{"total":{"value":3,"relation":"eq"},"max_score":1.0,"hits":[{"_index":"movies","_type":"movie","_id":"1","_score":1.0,"_source":{"title": "gangtie","director": "pfeiliu","year": 1999,"genres": ["nishishui", "asdwqe"]}},{"_index":"movies","_type":"movie","_id":"2","_score":1.0,"_source":{"title": "The Godfather","director": "Francis Ford Coppola","year": 1972,"genres": ["Crime", "Drama"]}},{"_index":"movies","_type":"movie","_id":"3","_score":1.0,"_source":{"title": "lawer","director": "lean","year": 1989,"genres": ["youar", "pl"]}}]}}
搜索某索引的数据类型
curl -H "Content-Type: application/json" -XGET "http://localhost:9200/movies/_search" {"took":1,"timed_out":false,"_shards":{"total":1,"successful":1,"skipped":0,"failed":0},"hits":{"total":{"value":3,"relation":"eq"},"max_score":1.0,"hits":[{"_index":"movies","_type":"movie","_id":"1","_score":1.0,"_source":{"title": "gangtie","director": "pfeiliu","year": 1999,"genres": ["nishishui", "asdwqe"]}},{"_index":"movies","_type":"movie","_id":"2","_score":1.0,"_source":{"title": "The Godfather","director": "Francis Ford Coppola","year": 1972,"genres": ["Crime", "Drama"]}},{"_index":"movies","_type":"movie","_id":"3","_score":1.0,"_source":{"title": "lawer","director": "lean","year": 1989,"genres": ["youar", "pl"]}}]}}
在指定索引中显式搜索指定类型的文档
curl -H "Content-Type: application/json" -XGET "http://localhost:9200/movies/movie/_search" {"took":1,"timed_out":false,"_shards":{"total":1,"successful":1,"skipped":0,"failed":0},"hits":{"total":{"value":3,"relation":"eq"},"max_score":1.0,"hits":[{"_index":"movies","_type":"movie","_id":"1","_score":1.0,"_source":{"title": "gangtie","director": "pfeiliu","year": 1999,"genres": ["nishishui", "asdwqe"]}},{"_index":"movies","_type":"movie","_id":"2","_score":1.0,"_source":{"title": "The Godfather","director": "Francis Ford Coppola","year": 1972,"genres": ["Crime", "Drama"]}},{"_index":"movies","_type":"movie","_id":"3","_score":1.0,"_source":{"title": "lawer","director": "lean","year": 1989,"genres": ["youar", "pl"]}}]}}
常见错误处理：
错误：{"error":"Content-Type header [application/x-www-form-urlencoded] is not supported","status":406}
解决：添加：-H "Content-Type: application/json"
错误：{"error":{"root_cause":[{"type":"mapper_parsing_exception","reason":"failed to parse"}],"type":"mapper_parsing_exception","reason":"failed to parse","caused_by":{"type":"json_e_o_f_exception","reason":"Unexpected end-of-input in field name\n at [Source: org.elasticsearch.common.bytes.BytesReference$MarkSupportingStreamInputWrapper@3c1b21d; line: 1, column: 133]"}},"status":400}curl: (3) unmatched close brace/bracket in URL position 5:
1972}
解决：在｛｝内的双引号都加上一个"\"转义
