弹性搜索Groovy脚本eachWithIndex [英] Elasticsearch Groovy Script eachWithIndex

问题描述

这是一个groovy脚本。问题是 ctx._source.academies.remove（index），因为ctx在那里不可见。索引变量是正确的...但我不能使用ctx。任何建议？

this is a groovy script. The problem is the ctx._source.academies.remove(index) because ctx is not visible there. The index variable is the right... but i cant use the ctx there. Any suggestions?

{
    "script" : "ctx._source.academies.eachWithIndex { it, index -> if(it['academy_id'] == academy_id) ctx._source.academies.remove(index) }",
    "params": {
        "academy_id": 344
    }
}

推荐答案

p>

Have you tried this?

ctx._source.academies.removeAll { it['academy_id'] == academy_id }

如果您需要检查 academy_id 匹配项目列表，则可以使用以下：（封闭应满足条件）

In case you need to check academy_id matching a list of items, then below can be used: (The closure should satisfy a criteria)

ctx._source.academies.removeAll { it['academy_id'] in [academy_id, some_other_id] }

从弹性搜索的角度来看，我认为脚本可以重写如下： / p>

From an elastic search perspective, I suppose the script can be rewritten as below:

{
    "script" : "ctx._source.academies.removeAll { it['academy_id'] in academy_ids }",
    "params": {
        "academy_ids": [344, 345, 346]
    }
}
