This problem is related with DSpace API, as the underlying functions do not provide such information. In some big collections this introduces performance problem too, as we need to read bigger portion of data than is to be served. Some time ago I posted a patch for this but it do not covers Oracle and other RDMBSs completely, so should be considered different way. > 2.

This issue has been rissen by Robin Taylor too. I haven't considered it as a problem before. It is currently reported on the JIRA list and will probably have a lower priority as there are other issues deemed more important.
