# Synchronize phonetic search keys

A fuzzy duplicate check with phonetic search rules applied, uses phonetic search keys to search for possible duplicate values. For better performance of duplicate checks, the phonetic search keys for existing data must be generated and synchronized regularly. The synchronized phonetic search keys are stored in the **DQSPhoneticKey** table.

To have up-to-date phonetic search keys, you are advised to synchronize the phonetic search keys several times per day. Regular synchronization of phonetic search keys is required due to:

- New or changed data on which fuzzy duplicate checks are done.
- New or changed fuzzy duplicate checks phonetic search setup.

On synchronization, phonetic search keys are created for:

- Active fuzzy duplicate checks.
- Only for the table fields with phonetic search setup.

The phonetic search keys are created considering the setup of the applicable phonetic search rule:

- Phonetic search algorithm.
- Maximum phonetic search key length.
- Words to be ignored.

### Steps

1. Click **Data quality management**.
2. Click **Duplicate checks**.
3. In the list, find and select the desired active duplicate check with at least one table field to which phonetic search is applied.
4. Click **Synchronize phonetic search keys**.
5. You can run the phonetic search keys synchronization for:

In the **Duplicate check name** field, type a value.
  - A specific duplicate check. In this case define the desired duplicate check.
  - All duplicate checks. in this case, leave the **Duplicate check name** field empty.
6. You can regenerate all phonetic search keys. Usually, you only do so when required. For example, when phonetic search duplicate checks don't return the expected results.

For performance reasons, usually, you run the recurring batch without regenerating all phonetic search keys.

Select **No** in the **Force recreate** field.
7. Sub-task: Set up recurring batch processing.
  1. Expand the **Run in the background** section.
  2. Select **Yes** in the **Batch processing field** and fill in the other fields as desired.
  3. Click **Recurrence** and fill in the fields as desired.
  4. Click **OK**.
8. Click **OK**.

> 
> In case of a Data Entry Workflow integration, when you create or change a record, and phonetic search is applicable, the phonetic search keys are created automatically.
