Stop Analyzer

Stop Analyzer

edit

The stop analyzer is the same as the simple analyzer but adds support for removing stop words. It defaults to using the _english_ stop words.

Definition

edit

It consists of:

Tokenizer
Token filters

Example output

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

The above sentence would produce the following terms:

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

Configuration

edit

The stop analyzer accepts the following parameters:

stopwords

A pre-defined stop words list like _english_ or an array containing a list of stop words. Defaults to _english_.

stopwords_path

The path to a file containing stop words. This path is relative to the Elasticsearch config directory.

See the Stop Token Filter for more information about stop word configuration.

Example configuration

edit

In this example, we configure the stop analyzer to use a specified list of words as stop words:

PUT my_index
{
  "settings": {
    "analysis": {
      "analyzer": {
        "my_stop_analyzer": {
          "type": "stop",
          "stopwords": ["the", "over"]
        }
      }
    }
  }
}

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

The above example produces the following terms:

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