That was pretty clear Ian. Thanks a lot.

All my fields are supposed to be searchable(indexed) and stored as well.I
was actually trying to leverage the new stored fields compression in 4.1.
So when I say,
IndexWriterConfig indexWriterConfig = new
IndexWriterConfig(Version.LUCENE_41, analyzer);
fieldType.setIndexed(true);
fieldType.setStored(true);
fieldType.setTokenized(false);
doc.add(new Field("published", b.getPublished(), fieldType));
This means that my docs will be indexed and stored in the compressed
format? Hope I am right this time? Thanks Ian.
