Yonik Seeley commented on LUCENE-352: ------------------------------------- +1 looks fine. > [PATCH] NullPointerException when using nested SpanOrQuery in SpanNotQuery > -------------------------------------------------------------------------- > > Key: LUCENE-352 > URL: http://issues.apache.org/jira/browse/LUCENE-352 > Project: Lucene - Java > Type: Bug > Components: Search > Versions: 1.4 > Environment: Operating System: Linux > Platform: Other > Reporter: Miles Barr > Assignee: Hoss Man > Attachments: LUCENE-352-consolidated-SpanNot-NPE.patch, > TestBasics.java.patch, TestBasicsPatch2.txt, patch.txt > > Overview description: > I'm using the span query classes in Lucene to generate higher scores for > search results where the search terms are closer together. In certain > situations I want to exclude terms from the span. When I attempt to exclude > more than one term I get an error. > > The example query I'm using is: > > 'brighton AND tourism' -pier -contents > > I construct the query objects and the toString() version is: > > spanNot(spanNear([contents:brighton contents:tourism], 10, false), > spanOr([contents:pier, contents:road])) > > > Steps to reproduce: > 1. Construct a SpanNearQuery (must have at least one term, but at least two > makes more sense) > 2. Construct a SpanOrQuery containing two or more terms > 3. Construct a SpanNotQuery to include the first query object and exclude the > second (SpanOrQuery) > 4. Execute the search > > > Actual Results: > A null pointer exception is thrown while generating the scores within the > search. > > Stack trace: > java.lang.NullPointerException > at > org.apache.lucene.search.spans.SpanOrQuery$1.doc(SpanOrQuery.java:174) > at > org.apache.lucene.search.spans.SpanNotQuery$1.next(SpanNotQuery.java:75) > at org.apache.lucene.search.spans.SpanScorer.next(SpanScorer.java:50) > > at org.apache.lucene.search.Scorer.score(Scorer.java:37) > at > org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:92) > at org.apache.lucene.search.Hits.getMoreDocs(Hits.java:64) > at org.apache.lucene.search.Hits.<init>(Hits.java:43) > at org.apache.lucene.search.Searcher.search(Searcher.java:33) > at org.apache.lucene.search.Searcher.search(Searcher.java:27) > at > com.runtimecollective.search.LuceneSearch.search(LuceneSearch.java:362) > > > Expected Resuts: > It executes the search and results where the first search terms (near query) > are close together but without the second terms (or query) appearing. -- 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]
