Question

我遇到一个简单的存在过滤器的问题。我想要实现的是，返回所有具有特定字段的文档。以下是他为我的索引绘图 -

"book": {
"dynamic": "true",
"properties": {
    "currencies": {
        "dynamic": "true",
        "properties": {
            "bookChallenge000": {
            "type": "long"
            },
            "achievements": {
            "type": "long"
            },

这是我要搜索的文件 -

我的查询非常简单，我需要所有具有挑战性的文档。

curl -X'GET' localhost:9200/book_index/_search -d '{"filter": {"exists" : { "field" : "challenges" }}}'

但它没有返回任何文件，我有100个带有挑战信息的文件。我尝试过meta.challenges，还有challenge.membersData，但它没有用。虽然如果我直接查找横幅或语言字段，我会得到预期的结果，但不能获得对象类型字段。

如何获取所有带有challenge或membersData的文档？

请告知我错过了什么。

这是您要查找的查询：

{
  "query": {
    "filtered": {
      "filter": {
        "bool": {
          "should": [
            {
              "exists": {
                "field": "meta.challenges"
              }
            },
            {
              "exists": {
                "field": "meta.membersData"
              }
            }
          ]
        }
      }
    }
  }
}

elasticsearch存在对象类型字段的过滤器
