Subject [jira] Commented: (LUCENE-1836) Flexible QueryParser fails with local different from en_US
Date Sun, 23 Aug 2009 01:42:14 GMT

Adriano Crestani commented on LUCENE-1836:
------------------------------------------

Hi,

I'm not being able to reproduce the problem, I tried to apply both patches and I got no error,
it passes fine on my eclipse env. Am I missing something?

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]

Yes, it seems a syntax limitation, the values cannot contain whitespace, if there is any whitespace
it expects the "TO" token. So it's a syntax limitation, but I see no reason to remove it and
allow whitespaces in the range values, considering anything between '[' or '{' to ' TO ' and
between ' TO ' to ']' or '}' as the range values, example: [<anyt_sequence_of_chars>
TO <any_sequence_of_chars>]

Thoughts?
