Simple analyzer

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

  1. POST _analyze
  2. {
  3.   "analyzer": "simple",
  4.   "text": "The 2 QUICK Brown-Foxes jumped over the lazy dog's bone."
  5. }

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

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

Definition

The simple analyzer is defined by one tokenizer:

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.

  1. PUT /my-index-000001
  2. {
  3.   "settings": {
  4.     "analysis": {
  5.       "analyzer": {
  6.         "my_custom_simple_analyzer": {
  7.           "tokenizer": "lowercase",
  8.           "filter": [                          
  9.           ]
  10.         }
  11.       }
  12.     }
  13.   }
  14. }
