I'm looking for the best approach for making changes (adding new fields) to a production setup full-text search index (added in 4.2) without having any downtime and affecting my clients.

Currently, the only way to accomplish this would be to create a 2nd index with your new definition, and then switch over in your application when the build is complete, and then delete the first index.

  • This answer needs to be updated because Atlas Search no supports no downtime re-indexing as long as you have enough disk spaces to support two copies of a search index. – Nice-Guy May 08 '22 at 18:13
