# Introduction to Index Actions

Index actions allow you to index content into Content Component, and to administer the Data index.

NOTE: Index actions are case sensitive. All index actions must be sent to the Content Component IndexPort.

You can control the users that can send index actions by configuring authorization roles. See Authorization Roles Configuration Parameters.

The following index actions are available:
