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.

Example

  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 ]

Definition

The simple analyzer is defined by one tokenizer:

Tokenizer

Lowercase Tokenizer

Customize

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": [ ] } } } } }
