# Index Data in a Distributed IDOL Setup

Configuration and indexing in a distributed system is very similar to using an individual IDOL Content component, except that you must configure multiple child servers, and send your index actions to the DIH, instead of Content.

In most cases, you use an identical or very similar configuration for each of your child IDOL Content components, even in non-mirror mode, to ensure that data is processed and indexed consistently. For example, you usually configure the same fields, languages, and databases, in all your child servers (although you might need to configure different port settings, and paths).

After you configure your child servers, you configure the DIH to distribute data to those child servers. For more information, refer to the DIH Administration Guide.

You send index actions (such as `DREADD` and `DREADDDATA`) to the DIH, which distributes the data to its child servers. Depending on your DIH configuration, DIH might also perform some preprocessing.
