问题描述

如何检查值是否包含字符串

How to check the value contain a string

下面是示例数据。我需要搜索任何属性，这些属性是 Thomas

Below is sample data. I need to search the any attributes which is Thomas

• 您可以看到我首先只有托马斯文件。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": "[e-mail]"
           },
       "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": "[e-mail]"
           },
       "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"
   }

推荐答案

您可以使用查询字符串在任何字段上搜索。

You can use query string to search on any field.

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，则希望搜索的默认字段。

default_field (Optional, string) Default field you wish to search if no field is provided in the query string.

默认为 index.query.default_field 索引设置，其默认值为 * 。 * 值提取所有符合条件查询的字段，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在一起以构建查询。

Defaults to the index.query.default_field index setting, which has a default value of *. The * value extracts all fields that are eligible for term queries and filters the metadata fields. All extracted fields are then combined to build a query if no prefix is specified.
