|DIH Engines section|
If you install and operate the DIH as Integrated with IDOL, you can configure child engines for DAH and DIH separately. This allows you increased flexibility when querying and indexing content in remote servers. For example, you could define multiple DIH child engines for content that you have to index through a combination of failover and mirroring.
Use the [DIHEngines] section to set the total number of IDOL servers to which the DIH sends index commands.
You must create a [DIHEngine<N>] subsection for each of the child engines to which DIH sends index commands, and in which you can specify the server's configuration details.
Note: This configuration for the DIH distribution child servers is not used for Standalone DIH.
