# Enable Deduplication for Individual Index Jobs

To enable deduplication for individual indexing jobs, use the KillDuplicates action parameter in the DREADD or DREADDDATA index actions.

You can use the KeepExisting action parameter when directly indexing data into the Content component with deduplication to reduce the indexing load.

You can use the following action parameters to move duplicates to a specified database.

- KillDuplicatesDB
- KillDuplicatesDBField
- KillDuplicatesMatchDBs
- KillDuplicatesMatchTargetDB
- KillDuplicatesPreserveFields

You can use any of the deduplication options with DREADD and DREADDDATA actions. When you use either of these actions:

- The KillDuplicates setting specified in either action overrides the same setting in the KillDuplicates configuration parameter.

- If you do not specify the KillDuplicates action parameter with either of the actions, the setting in the KillDuplicates configuration parameter is used.

## Use KeepExisting to Minimize the Index Load

If you set KillDuplicates to `Reference` or `FieldName`, you can use the KeepExisting action parameter to minimize the indexing load on Content when deduplicating.

Set KeepExisting to `True` to reverse normal deduplication and discard the document it has received for indexing and keep the existing matching document that it already contains instead.
