Indexing new documents is just adding additional segments. Adding new field to a document means: 1) Reading existing document (may not always be possible, depending on field configuration) 2) Marking existing document as deleted 3) Creating new document with reconstructed+plus new fields 4) Possibly triggering a marge if a lot of documents have been updated
Perhaps the above is a contributing factor. But I also feel that maybe there is some detail in your question I did not fully understand. Regards, Alex.
