ZCatalog: Index and Search for Zope objects
  
    Description

        ZCatalogs allow you to index and search for Zope objects.
        
        But ZCatalog is not just simply a data managemengt system that
        allows you to search through content. You have the choice
        which properties are stored in the Catalog and which
        attributes are used for searching.
        
        Once a set of objects is inserted into the Catalog, you will
        be able to update this object inventory by updating the
        objects, or deleting and adding them.
