# Configure View Server

IDOL View Server converts original documents into HTML format for viewing in a Web browser. It can also highlight search terms in the document, when displaying a search results. IDOL Data Admin uses IDOL View Server to create the document previews in searches.

There are three viewing modes. The appropriate one to use depends on how you index your documents, and your View Server configuration:

- Universal. In this mode, IDOL Data Admin requests document from a View Server that is configured in Universal Viewing mode. This mode allows View to use information in your data index to work out how to retrieve the original documents for viewing, by using a file, Web URL, or the Distributed Connector. To use this mode, you must enable universal viewing in your View Server configuration file. For more information, refer to the IDOL Server Administration Guide.

- Reference Field. In this mode, IDOL Data Admin requests documents from View Server by using a document reference field, which you can configure. In this case, the reference must be sufficient to identify the original location of the document, such as a URL or file path (if you configure IDOL View Server to view local files).

- Connector. In this mode, IDOL Data Admin uses a connector to retrieve the original document. The connector can retrieve the original document from the source repository, which simplifies the storage and retrieval. You must provide the host and port of the connector to use. IDOL Data Admin uses the `AUTN_IDENTIFIER` document field and connector group to request the original document.

  You can use any connector that supports the View action. If you want to retrieve documents from multiple repositories, you can use the Distributed Connector. For more information about the IDOL configuration for this set up, refer to IDOL Expert.

NOTE: If a document does not have the required reference field or connector group and identifier, IDOL Data Admin renders the title and document content from the Content index in the document previews. In this case, it uses the `DRETITLE` and `DRECONTENT` document fields to populate the title and content, respectively.

Users with the Administrator role can use the Settings pages to configure the IDOL View Server.

To configure IDOL View Server

1. In the toolbar on the top right of the page, click .

2. In the list, click Settings.

   The Settings page opens.

3. Find the View section, and specify the host and ACI port of your IDOL View Server.

4. From the Viewing Mode list, select the mode to use. Depending on the mode that you use, further options are required:

   - In Reference Field mode, specify the IDOL reference field to use to identify your documents in IDOL View Server.
   - In Connector mode, specify the host name and ACI port of the connector to use to retrieve documents.

5. Click Test Connection to ensure that IDOL Data Admin can connect to your IDOL View Server and Distributed Connector (if required).

   NOTE: In Universal mode, Test Connection checks the connection to the IDOL View Server, but does not check whether the other components that View needs to access are configured correctly. You must check any additional components in your View Server configuration.

6. Click Save Changes.
