Configuring language analyzersedit
Stopwordsedit
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 stemmingedit
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
, sorani
,
spanish
, swedish
, turkish
.
Reimplementing language analyzersedit
The built-in language analyzers can be reimplemented as custom
analyzers
(as described below) in order to customize their behaviour.
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
analyzeredit
The arabic
analyzer could be reimplemented as a custom
analyzer as follows:
PUT /arabic_example { "settings": { "analysis": { "filter": { "arabic_stop": { "type": "stop", "stopwords": "_arabic_" }, "arabic_keywords": { "type": "keyword_marker", "keywords": ["مثال"] }, "arabic_stemmer": { "type": "stemmer", "language": "arabic" } }, "analyzer": { "rebuilt_arabic": { "tokenizer": "standard", "filter": [ "lowercase", "decimal_digit", "arabic_stop", "arabic_normalization", "arabic_keywords", "arabic_stemmer" ] } } } } }
armenian
analyzeredit
