Otis Gospodnetic resolved LUCENE-548.
-------------------------------------

    Resolution: Won't Fix

I agree, doesn't seem worth fixing.  Explicit STRING is recommended.

>                 Key: LUCENE-548
>                 URL: https://issues.apache.org/jira/browse/LUCENE-548
>             Project: Lucene - Java
>          Issue Type: Bug
>          Components: Search
>    Affects Versions: 1.9
>         Environment: Linux 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.
