# Configuring built-in analyzers（配置内置分析器）

内置分析器可以直接使用，无需任何配置。然而，其中一些配置选项用来改变其行为。例如，standard(标准)分析器可以配置为支持停止词列表：

```
PUT my_index
{
  "settings": {
    "analysis": {
      "analyzer": {
        "std_english": {                              #1
          "type":      "standard",
          "stopwords": "_english_"
        }
      }
    }
  },
  "mappings": {
    "my_type": {
      "properties": {
        "my_text": {
          "type":     "text",
          "analyzer": "standard",                     #2
          "fields": {
            "english": {
              "type":     "text",
              "analyzer": "std_english"               #3
            }
          }
        }
      }
    }
  }}


POST my_index/_analyze
{
  "field": "my_text",                                 #4
  "text": "The old brown cow"}


POST my_index/_analyze
{
  "field": "my_text.english",                         #5
   "text": "The old brown cow"
}
```

| 1   | 我们将std\_english分析器定义为基于standard(标准)分析器，但是配置为删除预定义的英文停止词列表。                     |
| --- | ------------------------------------------------------------------------------ |
| 2，4 | my\_text字段直接使用standard（标准）分析器，无需任何配置。这个字段没有停止词会被删除。所得的词语是：\[the,old,brown,cow] |
| 3，5 | my\_text.english字段使用std\_english分析器，因此英文停止词将被删除。得出的结论是：\[old,brown.cow]        |
