# ValueRestriction

A string filter to apply to the returned tag values. The string can include Wildcard characters (`?`and `*`). You can specify multiple strings by separating the strings with commas. GetQueryTagValues returns only values for the specified FieldName fields that match one of the specified strings.

If your string contains commas, percent-encode the commas to distinguish them from separator commas, and then percent-encode the whole string again.

The specified `ValueRestriction` filter applies to the values in all the specified fields.

NOTE: If you set `ValueRestriction` and also set RestrictedValues to `True`, IDOL Server uses the `ValueRestriction` and ignores RestrictedValues.
