Hi Rama,
i think while creating search view you might missed 3 step. you havent provided the saved search over there see this pic.. this might be the problem.
you have to check that use saved search box and provide the ui object type also this might be problem because of that is not appearing over there..
i think you have added a button in the define buttons step this is for result view toolbar button if you observe Saved_search button is appearing in result view.
Thanks & Regards,
Srinivas.
