search behavior.
.. attribute:: ModelAdmin.show_full_result_count
.. versionadded:: 1.8
Set ``show_full_result_count`` to control whether the full count of objects
should be displayed on a filtered admin page (e.g. ``99 results (103 total)``).
If this option is set to ``False``, a text like ``99 results (Show all)``
is displayed instead.
The default of ``show_full_result_count=True`` generates a query to perform
a full count on the table which can be expensive if the table contains a
large number of rows.
