> This is a follow-up issue to LUCENE-8784.
> The KoreanNumberFilter is a TokenFilter that normalizes Korean numbers to
> regular Arabic decimal numbers in half-width characters.
> Logic is similar to JapaneseNumberFilter.
> It should be able to cover the following test cases.
> 1) Korean Word to Number
> 십만이천오백 => 102500
> 2) 1 character conversion
> 일영영영 => 1000
> 3) Decimal Point Calculation
> 3.2천 => 3200
> 4) Comma between three digits
> 4,647.0010 => 4647.001
