NearSpans

Key: LUCENE-569
URL: http://issues.apache.org/jira/browse/LUCENE-569
Project: Lucene - Java
Type: Bug
Components: Search
Reporter: Hoss Man
NearSpans appears to have a bug in skipTo that causes it to skip over some
matching documents completely. I discovered this bug while investigating
problems with SpanWeight.explain, but as far as I can tell the Bug is not
specific to Explanations ... it seems like it could potentially result in
incorrect matching in some situations where a SpanNearQuery is nested in
another query such thatskipTo will be used ... I tried to create a high level
test case to exploit the bug when searching, but i could not. TestCase
exploiting the class using NearSpan and SpanScorer will follow...
