[[analysis-lang-analyzer]] === Language Analyzers A set of analyzers aimed at analyzing specific language text. The following types are supported: <>, <>, <>, <>, <>, <>, <>, <>, <>, <>, <>, <>, <>, <>, <>, <>, <>, <>, <>, <>, <>, <>, <>, <>, <>, <>, <>, <>, <>, <>, <>, <>, <>. ==== Configuring language analyzers ===== Stopwords All analyzers support setting custom `stopwords` either internally in the config, or by using an external stopwords file by setting `stopwords_path`. Check <> for more details. ===== Excluding words from stemming The `stem_exclusion` parameter allows you to specify an array of lowercase words that should not be stemmed. Internally, this functionality is implemented by adding the <> with the `keywords` set to the value of the `stem_exclusion` parameter. The following analyzers support setting custom `stem_exclusion` list: `arabic`, `armenian`, `basque`, `bulgarian`, `catalan`, `czech`, `dutch`, `english`, `finnish`, `french`, `galician`, `german`, `hindi`, `hungarian`, `indonesian`, `irish`, `italian`, `latvian`, `lithuanian`, `norwegian`, `portuguese`, `romanian`, `russian`, `sorani`, `spanish`, `swedish`, `turkish`. ==== Reimplementing language analyzers The built-in language analyzers can be reimplemented as `custom` analyzers (as described below) in order to customize their behaviour. NOTE: If you do not intend to exclude words from being stemmed (the equivalent of the `stem_exclusion` parameter above), then you should remove the `keyword_marker` token filter from the custom analyzer configuration.
