Re: Deleted documents in the index.

[Michael McCandless]

When you call updateDocument, the old  document is deleted but a  
wholly new document is added.  So the "else" clause in your loop below  
will report on the newly added documents (you won't miss any).

Hi,
I think, the earlier mail didn't make it through.

I am writing a class to report on an index. This index has documents
updated using the IndexWriter.updateDocument(Term, Document) method.
That is, documents were deleted and added again. My aim is to see what
documents (and their fields) are present in the index. Since the
document was updated (i.e. deleted and added), it is marked as deleted
and hence not able to obtain a Document object for the updated
document.

How do I report on such documents ?

for (int i = 1; i < numDocs; i++) {
//ir is an IndexReader object
           if (ir.isDeleted(i)) {
               bw.write("Document " + i + " has been deleted.");
               bw.newLine();
           } else {
               Document d = getDocument(ir, i);

               List<Field> l = d.getFields();
               int numFields = l.size();
               bw.write("Document has " + numFields + " fields as  
follows");
               bw.newLine();

               for (int j = 0; j < numFields; j++) {
                   String fieldName = l.get(j).name();
                   bw.write("\t Field : " + fieldName + " Value : "
                           + d.getField(fieldName).stringValue());
                   bw.newLine();
               }
           }
       }
