如何在ElasticSearch中进行不分析？ [英] How to not-analyze in ElasticSearch?

问题描述

我在ElasticSearch领域有一个字段，我不想分析，我。即应逐字存储和比较。这些值将包含字母，数字，空格，破折号，斜杠以及其他字符。

如果我在此字段的映射中不给出分析器，则默认值使用一个将我的逐字符串字符串拼写成单词的标记器。我不想要这个。

有没有一个超简单的分析仪，基本上不分析？或者有不同的方式表示这个领域不会被分析？

我只创建索引，我不做任何其他事情。我可以使用像english这样的分析仪，其他字段似乎是预先配置的分析仪的内置名称。有没有其他名字的列表？也许有一个适合我的需要（即没有输入任何东西）。

这是我目前的映射：

  {
my_type：{
properties：{
my_field1：{type：string，analyzer english}，
my_field2：{type：string} 
} 
} 
} 
  pre> 
 
 
  my_field1 与语言有关;这似乎工作。  my_field2 应逐字进行。我想给一个分析器，根本不做任何事情。
 
 
 
  my_field2 的示例值将B45c 14/04。
解决方案
 
 code>my_field2：{
properties：{
title：{
type：string，
index：not_analyzed 
} 
} 
}

I've got a field in an ElasticSearch field which I do not want to have analyzed, i. e. it should be stored and compared verbatim.  The values will contain letters, numbers, whitespace, dashes, slashes and maybe other characters.

If I do not give an analyzer in my mapping for this field, the default still uses a tokenizer which hacks my verbatim string into chunks of words.  I don't want that.

Is there a super simple analyzer which, basically, does not analyze?  Or is there a different way of denoting that this field shall not be analyzed?

I only create the index, I don't do anything else.  I can use analyzers like "english" for other fields which seems to be built-in names for pre-configured analyzers.  Is there a list of other names?  Maybe there's one fitting my needs (namely doing nothing with the input).

This is my mapping currently:
{
  "my_type": {
    "properties": {
      "my_field1": { "type": "string", "analyzer": "english" },
      "my_field2": { "type": "string" }
    }
  }
}
my_field1 is language-dependent; this seems to work.  my_field2 shall be verbatim.  I'd like to give an analyzer there which simply does not do anything.

A sample value for my_field2 would be "B45c 14/04".
解决方案
"my_field2": {
    "properties": {
        "title": {
            "type": "string",
            "index": "not_analyzed"
        }
    }
}
