var children = parentContent.Children();

var parent = childContent.Parent();

var children = ((Kooboo.CMS.Content.Model.TextContent)ViewBag.Article).Children(commentSchema);

// Then you can also continuing add some filters on children queryable. For example:

children = children.WhereEquals("Published",true);

// If you are familiar with C#, you will find it is similar to LINQ.

// It is also easy to get all comments for all articles. There are two ways:

1. var allComments = commentSchema.CreateQuery();

2. var allArticleComments = articleFolder.CreateQuery().Children(commentSchema);

// As you see, get all comments for all articles, you just only remove that all filters.
