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.
