Simple analyzer

The simple analyzer breaks text into tokens at any non-letter character, such as numbers, spaces, hyphens and apostrophes, discards non-letter characters, and changes uppercase to lowercase.

				POST _analyze
					{
  "analyzer": "simple",
  "text": "The 2 QUICK Brown-Foxes jumped over the lazy dog's bone."
}
		

The simple analyzer parses the sentence and produces the following tokens:

[ the, quick, brown, foxes, jumped, over, the, lazy, dog, s, bone ]
		

The simple analyzer is defined by one tokenizer:

Tokenizer

• Lowercase Tokenizer

To customize the simple analyzer, duplicate it to create the basis for a custom analyzer. This custom analyzer can be modified as required, usually by adding token filters.

				PUT /my-index-000001
					{
  "settings": {
    "analysis": {
      "analyzer": {
        "my_custom_simple_analyzer": {
          "tokenizer": "lowercase",
          "filter": [
          ]
        }
      }
    }
  }
}
