  73                     on right FilterFactory-Service for all changes and synchronize right SfxFilterContainer with

  75                     We use given "sFactory" value to decide which query must be used to fill "pContainer" with new values.
  76                     Given "pContainer" hold us alive as uno reference and we use it to syschronize it with framework caches.
