# Configure View to Highlight Terms

You might need to add additional parameters to your configuration file to use View to highlight link terms in returned documents.

To configure View to highlight link terms

1. Open the IDOL View component configuration file in a text editor.

2. Find the `[Viewing]` section.

3. Set the following parameters in the `[Viewing]` section:

   `IDOLHost` | The host name where the IDOL Content component runs.
   `IDOLPort` | The value of the ACI port for this IDOL Content component.
   `IDOLTimeout` | The amount of time (in seconds) that View waits for a response from the IDOL Content component.

   These parameters determine where View sends `Highlight` actions. You must configure these parameters if you use View in a stand-alone configuration. If you use a unified IDOL Server, View uses the IDOL Content component in the IDOL Server, but you can configure these parameters if you want to use a different IDOL Content component.

   For information on using stand-alone components, refer to the IDOL Getting Started Guide.

4. Set `HighlightChunkSize` to the maximum size (in bytes) of the chunks that View splits text into before highlighting. Enter `–1` for an unlimited chunk size.

5. Set `DefaultLanguageType` to the language type that View uses for the link terms when highlighting. This parameter ensures that the IDOL Content component stems the terms correctly when highlighting. You can override this parameter by using the `LanguageType` parameter in the `View` action. See Highlight Expressions in Different Languages.

6. Set `DefaultStartTag` and `DefaultEndTag` to the default opening and closing HTML tags to use to highlight link terms.

7. Save and close the configuration file.

8. Restart the IDOL View component for your changes to take effect.
