token filter
editThe kuromoji_number
token filter normalizes Japanese numbers (kansūji)
to regular Arabic decimal numbers in half-width characters. For example:
PUT kuromoji_sample { "settings": { "index": { "analysis": { "analyzer": { "my_analyzer": { "tokenizer": "kuromoji_tokenizer", "filter": [ "kuromoji_number" ] } } } } } } GET kuromoji_sample/_analyze { "analyzer": "my_analyzer", "text": "一〇〇〇" }
Which results in:
{ "tokens" : [ { "token" : "1000", "start_offset" : 0, "end_offset" : 4, "type" : "word", "position" : 0 } ] }
