Subject [jira] Created: (LUCENE-549) Sort bug with ParallelMultiSearcher
Date Thu, 20 Apr 2006 04:43:34 GMT
Sort bug with ParallelMultiSearcher
-----------------------------------

         Key: LUCENE-549
         URL: http://issues.apache.org/jira/browse/LUCENE-549
     Project: Lucene - Java
        Type: Bug

  Components: Search  
    Versions: 1.9    
 Environment: FC2 Java 1.4.9
    Reporter: dan
    Priority: Minor



>>>>> Output:

java.lang.ClassCastException: java.lang.String
        at org.apache.lucene.search.FieldDocSortedHitQueue.lessThan(FieldDocSortedHitQueue.java:119)
        at org.apache.lucene.util.PriorityQueue.insert(PriorityQueue.java:61)
        at org.apache.lucene.search.MultiSearcherThread.run(ParallelMultiSearcher.java:271)

>>>>> Input:

- This only occurs when searching more than one index using ParallelMultiSearcher
- I use the signature new Sort( "date", true)
- The values in dates are strings in the form 20060419
- The call to getType in FieldDocSortedHitQueue misinterprets the value as an INT, then the
exception is thrown

>>>>> Available workaround

- I use the the signature new Sort(new SortField( "date", SortField.STRING, true)) and the
problem goes away.
