Steven Rowe updated LUCENE-1450:
--------------------------------
Attachment: LUCENE-1450.patch
This patch modifies the RangeTermEnum constructor as described, and includes
Danish tests in TestRangeQuery, TestRangeFilter, and TestMultiTermConstantScore
illustrating the problem -- these tests fail without the patch, and succeed
with it applied.
> RangeQuery & RangeFilter used with collation seek to lowerTerm using
> compareTo()

> Key: LUCENE-1450
> URL: https://issues.apache.org/jira/browse/LUCENE-1450
> Project: Lucene - Java
> Issue Type: Bug
> Affects Versions: 2.9
> Reporter: Steven Rowe
> Priority: Minor
> Fix For: 2.9

> Attachments: LUCENE-1450.patch

>
> The constructor for RangeTermEnum initializes a TermEnum starting with
> lowerTermText, but when a collator is defined, all terms in the given field
> need to be checked, since collation can introduce non-Unicode orderings.
> Instead, the RangeTermEnum constructor should test for a non-null collator,
> and if there is one, point the TermEnum at the first term in the given field.
> LUCENE-1424 introduced this bug.
