Property value

Type: System.Boolean
true to specify that the field is indexed; otherwise, false.


You attempted to set the property on a dependent field. Indexing is not available for dependent (or secondary) fields.


Although you can index a lookup column to improve performance, using an indexed lookup column to prevent exceeding the list view threshold does not work. Use another type of column as the primary or secondary index.
