Elasticsearch数组Array类型增加、删除

一、Array里边的元素是String

# 创建一条数据
POST test_index/test_type/1
{
  "tags":["tag1", "tag2", "tag3"]  
}

# 查看数据
GET test_index/test_type/1


# 给 _id=1 的tags增加一个 tag5
POST test_index/test_type/1/_update
{ "script" : { "source": "ctx._source.tags.add(params.tag)", "params" : { "tag" : "tag5" } }
}

# _id=1 的tags移除 tag5
POST test_index/test_type/1/_update
{ "script" : { "source": "ctx._source.tags.remove(ctx._source.tags.indexOf(params.tag))", "params" : { "tag" : "tag5" } }
}

# 查询 tag1 in tags 移除tag2
POST test_index/test_type/_update_by_query
{
  "query": { "term": { "tags": "tag1" }
  },
  "script": { "source": "ctx._source.tags.remove(ctx._source.tags.indexOf(params.tag))", "params": { "tag": "tag2" }
  }
}

二、Array里边包含对象

# 添加一条数据
POST /blog-test/doc/AXiHn9l3CFuw25Pb9kYM
{
  "title": "Invest Money",
  "body": "Please start investing money as soon...",
  "tags": [ "money", "invest"
  ],
  "published_on": "18 Oct 2017",
  "comments": [ { "name": "William", "age": 34, "rating": 8, "comment": "Nice article..", "commented_on": "30 Nov 2017" }, { "name": "John", "age": 38, "rating": 9, "comment": "I started investing after reading this.", "commented_on": "25 Nov 2017" }, { "name": "Smith", "age": 33, "rating": 7, "comment": "Very good post", "commented_on": "20 Nov 2017" }
  ]
}

# 数组添加一条数据
POST /blog-test/doc/AXiHn9l3CFuw25Pb9kYM/_update
{
  "script": { "source": "ctx._source.comments.add(params.new_comment)", "params": { "new_comment": { "name": "xiang", "age": 25, "rating": 18, "comment": "very very good article...", "commented_on": "3 Nov 2018" } }
  }
} # 数组移除一条数据
POST /blog-test/doc/AXiHn9l3CFuw25Pb9kYM/_update
{
  "script": { "lang": "painless", "source": "ctx._source.comments.removeIf(it -> it.name == 'John');"
  }
}

# 数组更新一条数据
POST /blog-test/doc/AXiHn9l3CFuw25Pb9kYM/_update
{
  "script": { "source": "for(e in ctx._source.comments){if (e.name == 'Smith') {e.age = 25; e.comment= 'very very good article...';}}"
  }
}
