If you're using C# then a simple if-else statement should work. Something like:

C#

..."Search Results:" + sessionStorage.getItem('getCount') == null ? 0 : (int)sessionStorage.getItem('getCount')

hi,
I gave like this
Search Results:" + sessionStorage.getItem('getCount') == null ? 0 :sessionStorage.getItem('getCount') + "
It is displaying only "null",not even displaying SearchResults: also

Though you not mentioned here what language you used for coding but it may be something like that...

C#

if(sessionStorage.getItem('getCount').toString() == '0')
  then print 0;  //or your preferred message
else
  Search Results:" + sessionStorage.getItem('getCount') + "  //your preferred work
