# FieldRestriction

When you have set Mode to `Index`, you can add a field restriction to the expansion to return only terms that appear in the specified field.

Set `FieldRestriction` to a list of the fields from which you want to return result terms. Separate multiple fields with colons (:). Query Manipulation Server adds the specified field restrictions to the `Text` parameter in the `TermExpand` action that it sends to the IDOL Server data index. For more information, refer to the IDOL Server Reference.

NOTE: The fields that you specify must be configured as `UnstemmedTrackFields` in the IDOL Server index.
