reader.document(i) and searcher.doc(i) do the same thing: retrieve the stored fields.
But neither method fully preserves indexing information; e.g., boosts are lost, details about how the field was indexed (e.g., DOCS_ONLY, et.c) are lost, etc. You can use the returned document to provide the values (strings, numbers) you want to index, but then you must re-assert your own schema by building a new document with Fields set up for indexing as you originally did, carrying over just the values you retrieved from the stored document.
