Stop Token Filter

Stop Token Filter

edit

A token filter of type stop that removes stop words from token streams.

The following are settings that can be set for a stop token filter type:

`stopwords`	A list of stop words to use. Defaults to `_english_` stop words.
`stopwords_path`	A path (either relative to `config` location, or absolute) to a stopwords file configuration. Each stop word should be in its own "line" (separated by a line break). The file must be UTF-8 encoded.
`ignore_case`	Set to `true` to lower case all words first. Defaults to `false`.
`remove_trailing`	Set to `false` in order to not ignore the last term of a search if it is a stop word. This is very useful for the completion suggester as a query like `green a` can be extended to `green apple` even though you remove stop words in general. Defaults to `true`.

The stopwords parameter accepts either an array of stopwords:

PUT /my_index
{
    "settings": {
        "analysis": {
            "filter": {
                "my_stop": {
                    "type":       "stop",
                    "stopwords": ["and", "is", "the"]
                }
            }
        }
    }
}

or a predefined language-specific list:

PUT /my_index
{
    "settings": {
        "analysis": {
            "filter": {
                "my_stop": {
                    "type":       "stop",
                    "stopwords":  "_english_"
                }
            }
        }
    }
}

Elasticsearch provides the following predefined list of languages:

_arabic_, _armenian_, _basque_, _brazilian_, _bulgarian_, _catalan_, _czech_, _danish_, _dutch_, _english_, _finnish_, _french_, _galician_, _german_, _greek_, _hindi_, _hungarian_, _indonesian_, _irish_, _italian_, _norwegian_, _persian_, _portuguese_, _romanian_, _russian_, _sorani_, _spanish_, _swedish_, _thai_, _turkish_.

For the empty stopwords list (to disable stopwords) use: _none_.
