token filter
editThe kuromoji_baseform
token filter replaces terms with their
BaseFormAttribute. This acts as a lemmatizer for verbs and adjectives. Example:
PUT kuromoji_sample { "settings": { "index": { "analysis": { "analyzer": { "my_analyzer": { "tokenizer": "kuromoji_tokenizer", "filter": [ "kuromoji_baseform" ] } } } } } } GET kuromoji_sample/_analyze { "analyzer": "my_analyzer", "text": "飲み" }
which responds with:
{ "tokens" : [ { "token" : "飲む", "start_offset" : 0, "end_offset" : 2, "type" : "word", "position" : 0 } ] }
