Addition of a new field doesn’t require reindexing. As you mentioned, after adding the new field, you can reload the core and update relevant docs via atomic/in-place updates.
Note: This is probably beside your original question, but note that atomic update in essence reconstructs the whole document internally, superimposes any new fields that you provide and reindexes it. So if your original document has a field that is non-stored, non-docValues, and is not a copy field target, it will be lost. -Rahul On Sat, Jan 3, 2026 at 9:51 AM Yaşar Arabacı <[email protected]> wrote: > Hi, > > I need to add a new field to an existing schema.
