paul.elschot commented on LUCENE-569: ------------------------------------- Hoss, There is an alternative NearSpans here: http://issues.apache.org/jira/browse/LUCENE-413 in the files: NearSpansOrdered.java NearSpansUnordered.java SpanNearQueryPatch1.txt It would be good to see whether these have the same skipTo bug. I'll have a look into this in a few days, please feel free to beat me to it. Anyway, thanks for the courage to review all of Lucene's use of Explanation. Explaining a score value is just as involved as the normal search mechanisms, as it is necessary to redo the whole search, but only for a single document, and then literally explain all the details in program code. > NearSpans skipTo bug > -------------------- > > Key: LUCENE-569 > URL: http://issues.apache.org/jira/browse/LUCENE-569 > Project: Lucene - Java > Type: Bug > Components: Search > Reporter: Hoss Man > Attachments: TestNearSpans.java > > 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... -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
