Software versions

Solr 8.1

Google Cloud Platform

New features

In the inaugural release, all features are new. These are highlights.


Managed Search provides REST APIs for:

  • Clusters: Create, update, and delete clusters.

  • Collections: Create, update, and delete collections.

  • Tasks: Get the status of long-running tasks (for cluster creation and deletion).


In addition to having the ability to manually scale a cluster, you can set up autoscaling:

  • Scheduled autoscaling
    Managed Search automatically scales the number of Solr nodes in a cluster to specified numbers at specified times on specified days. If no time is specified in a schedule entry, then the default time 00:00 UTC (Coordinated Universal Time) is used.

  • Search rate autoscaling
    Managed Search compares the actual average search rate across Solr nodes to the target average search rate (targetSearchRate). Managed Search adds and removes Solr nodes to keep the actual average search rate in the vicinity of the target search rate. The number of Solr nodes can range between a minumum (minNodes) and maximum (maxNodes).
