Ticket 47722 - Using the filter file does not work

Bug Description:  Using a filter file does not work correctly.  rsearch fails to
                  to use the filters from the file.

Fix Description:  There was a bug where we incorrectly freed each filter right after
                  we added it to the local list.  This left the list empty.
