Subject [jira] [Commented] (LUCENE-3922) Add Japanese Kanji number normalization to Kuromoji
Date Sun, 07 Oct 2012 00:11:03 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-3922?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13471117#comment-13471117

Lance Norskog commented on LUCENE-3922:
---------------------------------------

bq. On the other hand, I agree with Christian to not preserving leading zeros. So, "◯◯七"
doesn't need to become "007".
This example shows why leading zeros should be preserved :)

There are different kinds of text search. Searching for media titles like James Bond movies
is a very different thing from searching newspaper articles. You might want to find "◯◯七"
as the Japanese-language release and "007" as the English-language release. These numbers
are brands, not numbers.

> Japanese people use Kanji numerals instead of Arabic numerals for writing price, address
and so on. i.e 12万4800円(124,800JPY), 二番町三ノ二(3-2 Nibancho) and 十二月(December).
 So, we would like to normalize those Kanji numerals to Arabic numerals (I don't think we
need to have a capability to normalize to Kanji numerals).
