A software facility for selecting documents is disclosed. The facility maintains a dimensional model of a group of documents. The dimensional model reflects values for a number of differentiated attributes for each of the documents of the group. The facility receives a query specifying values for one or more of these attributes. In response to receiving the query, the facility uses the dimensional model to generate a list of documents in the group having the attribute values specified by the query.
