I need to add some more keywords to icu_tokanizer, which don't need to tokanize? i had tried kuromoji_tokanizer it has userdictionary, we can add new keyword tokens to userdictionary. can i have any way to do this to icu_tokanizer?
The ICU tokenizer doesn't appear to have a user dictionary, but uou can use rules files to customize the ICU tokenizer: ICU tokenizer | Elasticsearch Plugins and Integrations [8.12] | Elastic
You can also specify transform rules: ICU transform token filter | Elasticsearch Plugins and Integrations [8.12] | Elastic
I'm not sure if that'll get you where you want to go, though.
