This functionality is not related to finding similar or related content. For such functionality, use the `MoreLike` method, described in the [Searching](🔗) section.

Sometimes, to preserve consistency in the index, it is necessary to index not only saved/published content but also related content. For example, you indexed the child count for content and want it updated whenever "child content" is published.

To index related content, set the `RelatedContent` convention to return parent content when indexing. This way, parent content is reindexed and its child count is updated.
