# Enable Soundex Keyword Searches

NOTE: You must enable Soundex keyword searches before you index the data that you want to search.

To enable Soundex keyword searches

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

2. In the `[Server]` section, set the `Soundex` parameter to one of the following values. If the `[Server]` section does not contain the `Soundex` parameter, add it.

   1 | The IDOL Soundex extension.
   2 | Standard Soundex.
   4 | Double Metaphone.
   8 | The IDOL Double Metaphone extension.

3. Save and close the configuration file.

4. Restart the IDOL Content component for your changes to take effect.

5. Index documents into the IDOL Content component. After you finish indexing, you can perform Soundex keyword searches by using the `Query` action. The phonetic indexing and query uses the algorithm that you selected.
