Hi Ananth,
You have to add the child documents before the parent document,
otherwise the blockjoinquery won't work.

Hey guys,
I'm trying to index nested documents in lucene 3.6. I have
the parent document having a 'type' and 'typename' fields and the children
having 'value' and 'author' fields. The below snippet is what i've written
to index them as a block. Is this correct? Is there any working piece of
code i can use. Googling wasn't helpful.
private static void addDoc(IndexWriter w,String type, String
typename,String value, String author, String value2, String author2) throws
IOException {
ArrayList<Document> docs=new ArrayList<Document>();
Document doc = new Document();
doc.add(new Field("type", type, Field.Store.YES, Field.Index.ANALYZED));
doc.add(new Field("typename", typename, Field.Store.YES,
Field.Index.ANALYZED));
docs.add(doc);
Document doc1 = new Document();
doc1.add(new Field("value", value, Field.Store.YES,
Field.Index.ANALYZED));
doc1.add(new Field("author", author, Field.Store.YES,
Field.Index.ANALYZED));
docs.add(doc1);
Document doc2 = new Document();
doc2.add(new Field("value", value2, Field.Store.YES,
Field.Index.ANALYZED));
doc2.add(new Field("author", author2, Field.Store.YES,
Field.Index.ANALYZED));
docs.add(doc2);
w.addDocuments(docs);
}
Thanks,
Ananth.
