Emit a deprecation warning for ``Products.ZCatalog.CatalogAwareness``. The module was already deprecated according to its docstring. Since some five:deprecatedManageAddDelete directive in OFS always imports the module, we only emit the warning on actual use of the CatalogAware class.

Removed deprecated ``catalog-getObject-raises`` zope.conf option. The option was slated for removal in Zope 2.10.

Remove inline tutorial, this is better covered in http://docs.zope.org/zope2/zope2book/SearchingZCatalog.html

Avoid bare except's and catch Exception instead - this won't catch system exceptions like KeyboardInterrupt, MemoryError and similar things

Removed unmaintained HelpSys documents from ZCatalog and PluginIndexes. Useful explanations are given inside the form templates.

- no need to re-raise Redirect in raise_standardErrorMessage (ZPublisherExceptionHook is responsible for that)

More catalog work, merge in the non-queryplan and non-btree changes of queryplan and optimize more of date range index internals

Deprecate Products.ZCatalog's current behavior of returning the entire catalog content if no query restriction applied. In Zope 2.14 this will result in an empty LazyCat to be returned instead.

Deprecate acquiring the request inside Products.ZCatalog's searchResults method if no explicit query argument is given.
