Delete failed after new Term is indexed

           Summary: Delete failed after new Term is indexed
           Product: Lucene
           Version: 1.2
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Index
        AssignedTo: lucene-dev@jakarta.apache.org
        ReportedBy: tlai@leversoft.com


Deleting documents from a reader has no permanent effect if the reader is 
opened before a writer is used to index new documents.  This is similar to bug 
6140 (http://nagoya.apache.org/bugzilla/show_bug.cgi?id=6140) reported before, 
although I don�t think it is a multi-thread issue.  The following pseudo-code 
caused the problem:

reader.open()      
   
writer.open()            
writer.add(documentB) 
writer.close()      
    
reader.delete(documentA) 
reader.close()          

searcher.open()
searcher.search("term_common_to_docA_and_docB") 
// This returns both docA and docB

Please see my attached test class, which is single threaded.  I believe the 
option (a) and (b) suggested in BUG 6140 are valid, but not necessary (C).
