# 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 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 Content component runs.
   `IDOLPort` | The value of the ACI port for this Content component.
   `IDOLTimeout` | The amount of time (in seconds) that View waits for a response from the 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 configuration, View uses the internal Content component by default, but you can configure these parameters if you want to use a different Content component.

   For information on using stand-alone components, refer to the Knowledge Discovery 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 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 View component for your changes to take effect.
