-----------------------------------
Summary: corner case in MinShouldMatchSumScorer when there are
many terms
Key: LUCENE-4873
URL: https://issues.apache.org/jira/browse/LUCENE-4873
Project: Lucene - Core
Issue Type: Bug
Components: core/query/scoring
Affects Versions: 4.3
Reporter: Robert Muir
I think this bug is some extreme corner case...
This test currently only uses up to 9 terms. By increasing it to 26 and
blasting the test, I was able to uncover a bug.
Here's the seed: ant test -Dtestcase=TestMinShouldMatch2
-Dtests.method=testNextAllTerms -Dtests.seed=E0334C37E6E190D8 -Dtests.slow=true
-Dtests.locale=pl_PL -Dtests.timezone=Asia/Thimphu
-Dtests.file.encoding=US-ASCII
Here's the patch to make the test use 26 terms.
