This is the same issue that I mentioned to https://github.com/elastic/elasticsearch/issues/41401#event-2293189367
unlike standard analyzer, nori analyzer removes the decimal point.
nori tokenizer removes "." character by default.
In this case, it is difficult to index the keywords including the decimal point.
It would be nice if there had the option whether add a decimal point or not.
Like Japanese tokenizer does, Nori need an option to preserve decimal point.
