# Distributed Index Handler

The Distributed Index Handler (DIH) distributes index actions between multiple Content components.

DIH can either index all documents into multiple child servers, or it can distribute the documents evenly between them. Multiple identical copies of child servers allows load balancing and failover, while distributing the index allows you to store more content.
