org.apache.lucene.store.instantiated.InstantiatedIndexReader
@Deprecated public class InstantiatedIndexReader
An InstantiatedIndexReader is not a snapshot in time, it is completely in sync with the latest commit to the store!
Consider using InstantiatedIndex as if it was immutable.

public org.apache.lucene.document.Document document(int n,

IOException
Document at the nth
position.
Warning!
The resulting document is the actual stored document instance
and not a deserialized clone as retuned by an IndexReader
over a Directory.
I.e., if you need to touch the document, clone it first!
This can also be seen as a feature for live changes of stored values,
but be careful! Adding a field with an name unknown to the index
or to a field with previously no stored values will make
getFieldInfos()
out of sync, causing problems for instance when merging the
instantiated index to another index.
This implementation ignores the field selector! All stored fields are always returned!
