# Use a Community Component

If you want to use the QMS intent ranked query or intent based promotions functionality to promote results that are close to the interests of the user to the top of the result set, QMS must be able to communicate with a Community component. To set up communication with a Community component, you must perform one of the following tasks:

- Create a `[Community]` section in the configuration file, with `Host` and `Port` parameters that specify the host and port of the Community component that you want to use.

      [Community]
      Host=...
      Port=...

  Use this option if the `[IDOL]` section points to a DAH or IDOL Content server.

- Configure the `[IDOL]` section with the host and port of a unified IDOL server. If you use this option, no further configuration is required.

For more information on intent ranked queries and intent based promotions, see Intent Based Ranking and Intent Based Promotions, and refer to the QMS Reference.
