  • Procedure

Some Atlas Search features require that you update the index. To update your index, you can take one of the following actions:

  • Edit the index definition. To learn more about editing your index definition, see Edit an Atlas Search Index.

  • Opt-in for an index update from the Atlas UI. To opt-in for an index update, follow the steps in the Procedure on this page.

The process for updating the Atlas Search index requires time and resources. For the index update to complete successfully, allocate free disk space equal to 125% of your current index's disk space.

  3. If it's not already displayed, click Clusters in the sidebar.

    The Clusters page displays.

Go to the Atlas Search page for your cluster.

You can go the Atlas Search page from the sidebar, the Data Explorer, or your cluster details page.
