I see that Lucene 4.x has FieldInfo.IndexOptions that can be used to tell lucene whether to Index Documents/Frequencies/Positions/Offsets.
We are in the process of upgrading from Lucene 2.9 to Lucene 4.x and I was wondering if there was a way to tell lucene whether to index docs/freqs/pos/offsets or not in the older versions (2.9) or did it always index positions and offsets by default? Also I see that Lucene 4.x has FieldType.setStoreTermVectorPositions and FieldType.setStoreTermVectorOffsets. Can someone please tell me a usecase for storing positions and offsets in index? Is it necessary to store termvector positions and offsets when using IndexOptions.DOCS_AND_FREQS_AND_POSITIONS_AND_OFFSETS? Thanks -AarKay
