Thanks for the clarification.
This is a hefty limitation of the Lucene.
One would expect, that you would be able to update a specific field in
the index without having to reindex the entire document.

reader.document(i) and searcher.doc(i) do the same thing: retrieve the

But neither method fully preserves indexing information; e.g., boosts
