1、准备数据
PUT /lib/user/1 { "first_name":"Jane", "last_name":"Smith", "age":32, "about":"I like to collect rock albums", "interests":[ "music" ] }
2、操作演示
（1）age增加1
GET /lib/user/1/_update { "script":"ctx._source.age+=1" }
查看结果：GET /lib/user/1
{ "_index": "lib", "_type": "user", "_id": "1", "_version": 2, "found": true, "_source": { "first_name": "Jane", "last_name": "Smith", "age": 33, "about": "I like to collect rock albums", "interests": [ "music" ] } }
（2）改变last_name的值
GET /lib/user/1/_update { "script":"ctx._source.last_name+=‘hehe‘" }
查看结果：GET /lib/user/1
{ "_index": "lib", "_type": "user", "_id": "1", "_version": 3, "found": true, "_source": { "first_name": "Jane", "last_name": "Smithhehe", "age": 33, "about": "I like to collect rock albums", "interests": [ "music" ] } }
3）增加一个interests
GET /lib/user/1/_update { "script":{ "source":"ctx._source.interests.add(params.tag)", "params":{ "tag":"football" } } }
查看结果：GET /lib/user/1
{ "_index": "lib", "_type": "user", "_id": "1", "_version": 4, "found": true, "_source": { "first_name": "Jane", "last_name": "Smithhehe", "age": 33, "about": "I like to collect rock albums", "interests": [ "music", "football" ] } }
4）删除一个interests
GET /lib/user/1/_update { "script":{ "source":"ctx._source.interests.remove(ctx._source.interests.indexOf(params.tag))", "params":{ "tag":"football" } } }
查看结果：GET /lib/user/1
{ "_index": "lib", "_type": "user", "_id": "1", "_version": 5, "found": true, "_source": { "first_name": "Jane", "last_name": "Smithhehe", "age": 33, "about": "I like to collect rock albums", "interests": [ "music" ] } }
5）删除该文档，删除年龄为33的文档
GET /lib/user/1/_update { "script":{ "source":"ctx.op=ctx._source.age==params.count?‘delete‘:‘none‘", "params":{ "count":33 } } }
查看结果：GET /lib/user/1
{ "_index": "lib", "_type": "user", "_id": "1", "found": false }
6）有该文档的话给age增加1，没有添加一个文档
GET /lib/user/1/_update { "script":"ctx._source.age+=1", "upsert":{ "first_name": "Jane", "last_name": "Smith", "age": 18, "about": "I like to collect rock albums", "interests": [ "music" ] } }
查看结果：GET /lib/user/1
{ "_index": "lib", "_type": "user", "_id": "1", "_version": 1, "found": true, "_source": { "first_name": "Jane", "last_name": "Smith", "age": 18, "about": "I like to collect rock albums", "interests": [ "music" ] } }
