[ http://issues.apache.org/jira/browse/LUCENE-413?page=all ]
paul.elschot updated LUCENE-413:
--------------------------------
Attachment: DisjunctionSumScorerPatch5.txt
Patch for org.apache.lucene.search.DisjunctionSumScorer.java .
This query was reported by Ramana Jelda on java-user to have the same problem:
+(
+(
spanNear([productName:mp, productName:3], 3, true)
spanNear([subName:mp, subName:3], 3, true)
)
+(productName:player subName:player)
)
Looking at the query structure and the one reported earlier, I realized the bug
could also be in DisjunctionSumScorer.skipTo(), and not in the span query code.
Now let's hope this does it...
