> 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.
