Language analyzers [analysis-lang-analyzer]

A set of analyzers aimed at analyzing specific language text. The following types are supported: arabic, armenian, basque, bengali, brazilian, bulgarian, catalan, cjk, czech, danish, dutch, english, estonian, finnish, french, galician, german, greek, hindi, hungarian, indonesian, irish, italian, latvian, lithuanian, norwegian, persian, portuguese, romanian, russian, serbian, sorani, spanish, swedish, turkish, thai.

Configuring language analyzers [_configuring_language_analyzers]

Stopwords [_stopwords]

All analyzers support setting custom stopwords either internally in the config, or by using an external stopwords file by setting stopwords_path. Check Stop Analyzer for more details.

Excluding words from stemming [_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 keyword_marker token filter with the keywords set to the value of the stem_exclusion parameter.

The following analyzers support setting custom stem_exclusion list: arabic, armenian, basque, bengali, bulgarian, catalan, czech, dutch, english, finnish, french, galician, german, hindi, hungarian, indonesian, irish, italian, latvian, lithuanian, norwegian, portuguese, romanian, russian, serbian, sorani, spanish, swedish, turkish.

Reimplementing language analyzers [_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. ::::

arabic analyzer [arabic-analyzer]

The arabic analyzer could be reimplemented as a custom analyzer as follows:

PUT /arabic_example
{
  "settings": {
    "analysis": {
      "filter": {
        "arabic_stop": {
          "type":       "stop",
          "stopwords":  "_arabic_" <1>
        },
        "arabic_keywords": {
          "type":       "keyword_marker",
          "keywords":   ["مثال"] <2>
        },
        "arabic_stemmer": {
          "type":       "stemmer",
          "language":   "arabic"
        }
      },
      "analyzer": {
        "rebuilt_arabic": {
          "tokenizer":  "standard",

            "arabic_keywords",
            "arabic_stemmer"
          ]
        }
      }
    }

          ]
        }
      }
    }
  }
}
