elasticsearch - 有没有办法从脚本访问 "inner_hits"数据

Question

来自带有 "has_child" 子句和 inner_hits 的查询的响应文档具有类似于以下的结构:

 "hits": {
    ...
    "hits": [
      {
        METADATA
        "_source": {
            ...
        },
        "inner_hits": {
            INNER HITS DATA
        }
      },
      ....

有没有办法从 Groovy 脚本访问 inner_hits 内容？

Answer 1

不，你不能:

参见 here

It is not possible, in any scripting language (not just painless). Inner hits are completely separate documents within lucene, but scripts operate on a single document at a time.
