使用javascript API从数组中删除满足弹性搜索条件的对象 [英] remove objects from array that satisfying the condition in elastic search with javascript api
本文介绍了使用javascript API从数组中删除满足弹性搜索条件的对象的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
假设我的弹性搜索文档中有一个数组类型字段,如下所示:-
Suppose I have a array type field in my document of elastic search, like below:-
"prog_lists": [
{
"description": "engineer",
"age": 25,
"name": "ashu"
},
{
"description": "programmer",
"age": 26,
"name": "rajit"
},
{
"description": "designer",
"age": 27,
"name": "naveen"
}
]
我想删除名称等于ashu的对象,或者删除满足查询条件的多个对象,例如年龄大于25岁的
I want to remove objects which have name equals to ashu, or remove multiple object which satisfy the query like whose age is greater then 25
我可以通过指定对象内的所有内容来做到这一点,如下所示:-
I am able to do this by specifying all the things within object like below:-
client.update({
"index": "daffo_netgear",
"type": "array",
"id": "2201",
"body": {
"script":"ctx._source.prog_lists.remove(list)",
"params" : {
"list" :{
"description": "engineer",
"age": 25,
"name": "ashu"
}
}
}})
但是我只想指定姓名或年龄
but i want to do this just specifying name or age
client.update({
"index": "daffo_netgear",
"type": "array",
"id": "2201",
"body": {
"script":"ctx._source.prog_lists.remove(list)",
"params" : {
"list" :{
"name": "ashu"
}
}
}})
我的节点模块弹性搜索版本是2.4.2弹性搜索服务器是1.3.2.
My node module elastic search version is 2.4.2 elastic search server is 1.3.2.
推荐答案
我已经回答了,它的解决方案是
POST /twitter/twit/1/_update
{
"script": "item_to_remove = nil; foreach (item : ctx._source.list) { if (item['tweet_id'] == tweet_id) { item_to_remove=item; } } if (item_to_remove != nil) ctx._source.list.remove(item_to_remove);",
"params": {"tweet_id": "123"}
}
如果您有多个符合条件的项目,请改用列表:
POST /twitter/twit/1/_update
{
"script": "items_to_remove = []; foreach (item : ctx._source.list) { if (item['tweet_id'] == tweet_id) { items_to_remove.add(item); } } foreach (item : items_to_remove) {ctx._source.list.remove(item);}",
"params": {"tweet_id": "123"}
}
