I am using updateDocument() method to update my document in the lucene index. Here is how I am doing it.

writer.updateDocument(new Term(Constants.DOC_ID_FIELD, doc.get(Constants.DOC_ID_FIELD)), doc);

I check my index data with Luke, and find that on second run of the indexing, Luke tells that Deleted Document - not available. So basically, the document is marked as deleted, but it still resides in the index.

I don’t want to keep these marked deleted documents. Am I doing it wrong?

Also, my understanding was that, when I am updating the document, it deletes the old one and then adds the new one. Is that not the case?

    Got the answer from the mailing list.

    IndexWriter.updateDocument() deletes and then adds. So your index will have deleted docs. Why do you care? They’ll go away eventually as segments get merged.

    If you really do care, see IndexWriter,forceMergeDeletes(). See also
    the javadoc for that: This is often a horribly costly operation; rarely is it warranted.
