> CachingIndexReader.document(int n, FieldSelector fieldSelector) creates a new
> Field from the cached UUID. The lucene Field implementation always does a
> String.intern() on the field name, which is quite slow. We should probably have
> our own implementation for that specific use case where we know that the name
> is already interned. e.g. UUIDField implements Fieldable.
