[jira] Updated: (LUCENE-421) Numeric range searching with large value sets

     [ http://issues.apache.org/jira/browse/LUCENE-421?page=all ]

Antoine updated LUCENE-421:
---------------------------

    Attachment: IntegerRangeQueryTestCase.java

I juste made some junit test using some IntegerRangeQuery's, and I get
some strange results.
I attached the junit test I used. It fails on the last assert. I am
expecting only one result: the date between 1981 and 1983, but I get 2
The test output is:

term = date:1980
term = date:1982
term = date:1984
RangeQuery q = date:[1981 TO 1983]
Document<stored/uncompressed,indexed,tokenized<date:1982>>
IntegerRangeQuery q = date=[1981 TO 1983]
Document<stored/uncompressed,indexed,tokenized<date:1982>>
Document<stored/uncompressed,indexed,tokenized<date:1984>>
