# Optional IDOL Components

The following IDOL components are optional:

- IDOL Query Manipulation Server (QMS) 12.9 (Find requires access to the ACI and service ports).

  NOTE: IDOL QMS sends queries to an IDOL Content component data index. The IDOL Content component that you use must be the same for both QMS and the Find configuration (see Required IDOL Components).

  IDOL QMS also requires an IDOL Agentstore subcomponent. However, you do not need to configure the details of the IDOL QMS Agentstore component in Find.

- IDOL Statistics Server 11.3.0 (Find requires access to the ACI and service ports).

- IDOL Answer Server 12.9 (Find requires access to the ACI and service ports).

- IDOL Agentstore component 12.9 (Find requires access to the ACI and service ports).

  NOTE: Your IDOL Community component must have access to an Agentstore component. However, Find needs access only if you want to configure the related users tab. See Configure the Related Users Tab.
