Google Custom Search returning too many pages

Question

In our site we have a custom google search. When you do a search all ten paginated pages come back, however the last three or four will be empty and just display "No Results"

from what I've been reading, this shouldn't happen. If there are no results on the page then it should redirect you to the last page that does have content. Is there an attribute to make sure this happens?

the code looks something like this

      (function() {                                                                                    
  var id= '#id#'; // Insert your own Custom Search engine ID here                                     
      var gcse = document.createElement('script'); gcse.type = 'text/javascript'; gcse.async = true;   
      gcse.src = (document.location.protocol == 'https' ? 'https:' : 'http:') +                        
              '//www.google.com/cse/cse.js?cx=' + id;                                                  
      var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(gcse, s);          
  })();    

and then

 <gcse:searchresults-only ></gcse:searchresults-only> 

Answer 1

Have you tried using the resultSetSize attribute to limit the result set? This should limit to a maximum of 10 pages with 10 results per page. If there are fewer results, you shouldn't get 10 records. I believe the default here is 10 in place of filtered_cse.

<gcse:searchresults-only resultSetSize="filtered_cse"></gcse:searchresults-only>
