Define nodes that represent queries/searches, with children representing the results of the searches

DNA should provide a way for a search to be saved as a node and for the results of the search be shown as children of the node. One way is to define a query node (with the query stored on the node), and to find these and interpret these. Another is to create a "search repository source" with a node per query and the location(s) where each query node is to be projected; the source would then be able to return the results of the query as children. This latter approach would be beneficial in that the query could define the results be returned organized into different facets, and these facets be returned as children with the results (or remaining facets) be returned below the facets. (See also DNA-199 for a similar feature based upon data in a SQL database.)
