Our database server (SIM) has a facility for querying a database at regular intervals. The results are masked with a last-modified filter, which is updated each time the query is issued. This means that users can run a session, build up queries (either by creating new ones, or merging prior result sets with boolean operators) and then save them. They can then have those saved queries executed regularly on any new or changed data and a notification sent to them in an appropriate manner (e.g. an emailed page of abstracts and accompanying links). The beauty of this approach is that is conflates the concept of filter and query. Hence, users wishing to filter documents for items of interest have the full expressive querying power of the database with which to define their peculiar interests.
