Robert Muir commented on LUCENE-1836:
-------------------------------------
I played with this korean issue some, I am not sure what the fix should be (I
am not too terribly familiar with the new qp, so that doesn't help).
The issue is that under the korean locale, the query cannot be parsed.
I believe the problem is that korean date format for this date (2/1/2002) look
like "02. 2. 1"
so the qp gives parsing errors, cannot parse ranges like [ 02. 2. 1 TO 02. 2. 4]
Guessing this is due to whitespace present in korean date format?
Set your locale in setUp() to Locale.setDefault(Locale.KOREA) to see the
problem...
