(2) I understand Luke is able to reconstruct the field so that the document can be re-inserted. Can someone give me a hint on how its done and if its potentially too time consuming for a large index (up to million docs and too many terms to count).
Luke simply iterates over all terms, and collects terms and their positions in a selected document, and then builds an array of terms, inserting them at correct positions. If there are gaps in positions, it inserts nulls.
For a large index with many terms this could take long (an hour?) - whether it's a viable option to you depends on the value you put on that document's data, and how often you need to do this ...
