ES数据库对象与关系型数据库对象对比
Relational DB -> Databases -> Tables -> Rows -> Columns
Elasticsearch -> Indices -> Types -> Documents -> Fields
语法
curl -X<VERB> ‘<PROTOCOL>://<HOST>/<PATH>?<QUERY_STRING>‘ -d ‘<BODY>‘
curl -XPUT "http://172.16.101.54:9200/megacorp/employee/1?pretty" -H ‘Content-Type: application/json‘ -d ‘ { "first_name" : "John", "last_name" : "Smith", "age" : 25, "about" : "I love to go rock climbing", "interests" : [ "sports" , "music" ] } ‘ curl -XPUT "http://172.16.101.54:9200/megacorp/employee/2?pretty" -H ‘Content-Type: application/json‘ -d ‘ { "first_name" : "Jane", "last_name" : "Smith", "age" : 32, "about" : "I like to collect rock albums", "interests" : [ "music" ] } ‘ curl -XPUT "http://172.16.101.54:9200/megacorp/employee/3?pretty" -H ‘Content-Type: application/json‘ -d ‘ { "first_name" : "Douglas", "last_name" : "Fir", "age" : 35, "about" : "I like to build cabinets", "interests" : [ "forestry" ] } ‘ $ curl -XGET "http://172.16.101.54:9200/_cat/indices?v" health status index uuid pri rep docs.count docs.deleted store.size pri.store.size yellow open megacorp GqtIJQM-RtiqJCxDtyj5Zg 5 1 3 0 16.8kb 16.8kb
$ curl -XGET "http://172.16.101.54:9200/megacorp/employee/1?pretty" { "_index" : "megacorp", "_type" : "employee", "_id" : "1", "_version" : 1, "found" : true, "_source" : { "first_name" : "John", "last_name" : "Smith", "age" : 25, "about" : "I love to go rock climbing", "interests" : [ "sports", "music" ] } }
$ curl -XGET "http://172.16.101.54:9200/megacorp/employee/_search?pretty" { "took" : 8, "timed_out" : false, "_shards" : { "total" : 5, "successful" : 5, "failed" : 0 }, "hits" : { "total" : 3, "max_score" : 1.0, "hits" : [ { "_index" : "megacorp", "_type" : "employee", "_id" : "2", "_score" : 1.0, "_source" : { "first_name" : "Jane", "last_name" : "Smith", "age" : 32, "about" : "I like to collect rock albums", "interests" : [ "music" ] } }, { "_index" : "megacorp", "_type" : "employee", "_id" : "1", "_score" : 1.0, "_source" : { "first_name" : "John", "last_name" : "Smith", "age" : 25, "about" : "I love to go rock climbing", "interests" : [ "sports", "music" ] } }, { "_index" : "megacorp", "_type" : "employee", "_id" : "3", "_score" : 1.0, "_source" : { "first_name" : "Douglas", "last_name" : "Fir", "age" : 35, "about" : "I like to build cabinets", "interests" : [ "forestry" ] } } ] } }
例如搜索员工姓氏中包含“Smith”的员工
$ curl -XGET "http://172.16.101.54:9200/megacorp/employee/_search?pretty=true&q=last_name:Smith" { "took" : 5, "timed_out" : false, "_shards" : { "total" : 5, "successful" : 5, "failed" : 0 }, "hits" : { "total" : 2, "max_score" : 0.2876821, "hits" : [ { "_index" : "megacorp", "_type" : "employee", "_id" : "2", "_score" : 0.2876821, "_source" : { "first_name" : "Jane", "last_name" : "Smith", "age" : 32, "about" : "I like to collect rock albums", "interests" : [ "music" ] } }, { "_index" : "megacorp", "_type" : "employee", "_id" : "1", "_score" : 0.2876821, "_source" : { "first_name" : "John", "last_name" : "Smith", "age" : 25, "about" : "I love to go rock climbing", "interests" : [ "sports", "music" ] } } ] } }
采用DSL方式查询
$ curl -XGET ‘http://172.16.101.54:9200/megacorp/employee/_search?pretty=true‘ -d ‘{ "query" : { "query_string" : { "query" : "last_name:Smith" } } } ‘ { "took" : 8, "timed_out" : false, "_shards" : { "total" : 5, "successful" : 5, "failed" : 0 }, "hits" : { "total" : 2, "max_score" : 0.2876821, "hits" : [ { "_index" : "megacorp", "_type" : "employee", "_id" : "2", "_score" : 0.2876821, "_source" : { "first_name" : "Jane", "last_name" : "Smith", "age" : 32, "about" : "I like to collect rock albums", "interests" : [ "music" ] } }, { "_index" : "megacorp", "_type" : "employee", "_id" : "1", "_score" : 0.2876821, "_source" : { "first_name" : "John", "last_name" : "Smith", "age" : 25, "about" : "I love to go rock climbing", "interests" : [ "sports", "music" ] } } ] } }
$ curl -XGET ‘http://172.16.101.54:9200/megacorp/employee/_search?pretty=true‘ -d ‘{ "query" : { "match" : { "last_name" : "Smith" } } } ‘ { "took" : 10, "timed_out" : false, "_shards" : { "total" : 5, "successful" : 5, "failed" : 0 }, "hits" : { "total" : 2, "max_score" : 0.2876821, "hits" : [ { "_index" : "megacorp", "_type" : "employee", "_id" : "2", "_score" : 0.2876821, "_source" : { "first_name" : "Jane", "last_name" : "Smith", "age" : 32, "about" : "I like to collect rock albums", "interests" : [ "music" ] } }, { "_index" : "megacorp", "_type" : "employee", "_id" : "1", "_score" : 0.2876821, "_source" : { "first_name" : "John", "last_name" : "Smith", "age" : 25, "about" : "I love to go rock climbing", "interests" : [ "sports", "music" ] } } ] } }
