 Some important utilities include:
 
-- a **catalog**: the catalog has the responsibility to index every content properties which are required to make quick
-  and efficient searches. Catalog indexes are automatically created on database upgrade; management interface
-  allows administrator to get indexes properties, to get the number of indexed objects and values for a given index, and
-  to delete an index before recreating it by running the database upgrade script another time (see :ref:`scripts`).
