Get a HierarchySupportList from HierarchyFilter.NewList. A HierarchySupportList is returned if HierarchyFilter.KeepHierarchical is true. Otherwise a FactoryList is returned.
The HierarchySupportList contains the objects at the top level of the search tree that match the filter, and those objects at the top level that have descendents that match the filter. To determine whether an item in the list matches the filter check the IsInFilter Property. If the property is false, the item does not match the filter, but has descendent that match.
To search for matches in a sub-tree, specify the root of the sub-tree with a filter on RQ_FATHER_ID. The search begins with the children of the specified node. The item having the specified RQ_FATHER_ID is not checked.
If there is no filter on RQ_FATHER_ID, the entire tree is searched. If any item matches, the list contains the root node of the tree.
