如何检查值是否包含字符串

下面是示例数据。我需要搜索Thomas

的任何属性

您可以看到第一份文件中只有Thomas。因此，第一个文件必须返回。基本上一个文档（如果存在任何搜索字段）我需要检索该文档

   {
       "id": "Accounting 101",
       "dataproduct": "E3",
       "professor": {
           "name": "Thomas Baszo",
           "department": "finance",
           "facutly_type": "part-time",
           "email": "baszot@onuni.com"
           },
       "students_enrolled": 27,
       "course_publish_date": "2015-01-19",
       "course_description": "Act 101 is a course from the business school on the introduction to accounting that teaches students how to read and compose basic financial statements"
   }
   
   PUT /data/test/2
   {
       "name": "Accounting 101",
       "room": "E3",
       "professor": {
           "name": "Sachin Baszo",
           "department": "finance",
           "facutly_type": "part-time",
           "email": "baszot@onuni.com"
           },
       "students_enrolled": 27,
       "course_publish_date": "2015-01-19",
       "course_description": "Act 101 is a course from the business school on the introduction to accounting that teaches students how to read and compose basic financial statements"
   }

您可以使用query string搜索任何字段。

GET /_search
{
  "query": {
    "query_string": {
      "query": "Thomas"
    }
  }
}

default_field （可选，字符串）如果查询字符串中未提供任何字段，则为您要搜索的默认字段。

默认为index.query.default_field索引设置，其默认值为*。 *值提取符合条件查询的所有字段，并过滤元数据字段。如果未指定前缀，则将所有提取的字段组合起来以构建查询。

如何使用DSL查询搜索所有属性？
