Edit an Atlas Search Index¶

You can change the index definition of an existing Atlas Search index. You cannot rename an index; if you need to change an index’s name, you must create a new index and delete the old one.

Note

When you change the index definition of an Atlas Search index, the index must rebuild. You should avoid running queries against an Atlas Search index while it is building, as they may return incomplete results.

To rebuild an index without downtime:

Create a copy of the index with a new name and the desired configuration.
Update your queries to use the new index.
Delete the old index.
