# Child Field Index

When checked, the field is indexed; when unchecked, the field is not indexed. This may be used, therefore, to explicitly remove an already-defined field from the index.

## [](#example)Example

> [!NOTE]
> When this checkbox is checked, the resulting index will proportionately increase in size.
