在弹性搜索中将数字字段索引为int和string [英] indexing numeric field as both int and string in elastic search

问题描述

如何使用multi_field将数字字段作为整数和字符串进行索引。由于multi_field现在已被弃用。如何使用版本2.x中的fields字段实现相同的操作。我听说过一个领域可以使用领域以不同的方式索引和分析。但是，在弹性搜索中可以将其作为不同的类型进行索引吗？

How can I index a numeric field as both a integer and string using multi_field . As multi_field is deprecated now. How can I achieve the same using the "fields" field in version 2.x. I have heard that a field can be indexing and analysed in different ways using "fields". But can it be indexed as different types in elastic search?

我所面临的问题是弹性搜索中的古典数字字段搜索突出问题，我无法获得数字字段突出显示。所以我想将字段索引为字符串和int，以便我可以搜索，突出显示和对数据执行范围操作。

The issue that I am facing is the classical numeric field search highlighting issue in elastic search.where I could not get numeric fields highlighting. So I want to index the field as string and int so that I can search, highlight and perform range operations on the data.

推荐答案

您可以使用字段将您的数字 string 以及

You can use fields like this to have your numeric as string as well:

{
  "mappings": {
    "test": {
      "properties": {
        "my_numeric": {
          "type": "integer",
          "fields": {
            "as_string": {
              "type": "string",
              "index": "not_analyzed"
            }
          }
        }
      }
    }
  }
}
