true to specify that the field is indexed; otherwise, false.

ExceptionCondition

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

NoteNote

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.
