An improved technique of querying a data store by widening the query using a series of queries that follow relations between items. Initial auxiliary queries are used to find metadata property values (rather than the actual items) that are then used in the subsequent queries. The initial queries employ one or more property values to find a related item. In response thereto, an action menu is presented for the item that facilitates widening the search for all other items with the same selected property value. The user can be presented with several choices depending on which property is used for query widening.
