elasticsearch Elasticsearch：查找包含数组字段的所有文档，数组字段可以为空或非空

请在我的elasticsearch 7.7.0中找到以下示例文档。如何构建优化查询以获取包含数组字段的所有文档。如您所见，有些文档没有此字段，有些文档的值为null。需要获取此字段为空数组或数组中有某些项的文档。需要删除缺少字段或字段为空的文档

示例文档：

[
     {
       "_index" : "test",
       "_type" : "_doc",
       "_id" : "5",
       "_score" : 1.0,
       "_source" : {
         "severity" : 5,
         "problemInvestigations" : [
           {
             "Request ID01" : "PBI000000000001",

我在下面运行查询，但没有得到任何文档。请建议

GET test/_search
{
  "query": {
    "bool": {
      "filter": {
        "script": {
          "script": """
            if (doc.containsKey('problemInvestigations') && doc['problemInvestigations'].values.length >= 0) {
              return true;
            }else{
              return false;
            }
          """
        }
      }
    }
  }
}
