kuromoji_number token filter
editkuromoji_number 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
} ]
}
