Google Custom Search Engine API - lowRange, highRange, startNum

In line #2, with parameter "highRange":"19800","inputEncoding":"utf8","lowRange":"19700" get total 3 search results with the custom engine.

But in line #50, with parameter "highRange":"19900","inputEncoding":"utf8","lowRange":"19800" get total 0 search results....

And again in line #103, with parameter "highRange":"20000","inputEncoding":"utf8","lowRange":"19900" get total 4840 results...



What is the lowRange and highRange exactly???

highRangestring
  • Specifies the ending value for a search range.
  • Use lowRange and highRange to append an inclusive search range of lowRange...highRange  to the query.
One  of the most relevant answer in Google group is: 

-------------------------------
In my opinion you could get all the results using the lowRange and High Range properties of the query, and putting values higher than 100
I am using the .net interface and it would look like that:

 CustomsearchService svc = new CustomsearchService();
                    svc.Key = apiKey;
                    
                    Google.Apis.Customsearch.v1.CseResource.ListRequest listRequest = svc.Cse.List(query);
                    listRequest.Cx = cx;
                    
                    listRequest.Start = 0; 
                    listRequest.Num = 10; 
                    listRequest.LowRange = "100";
                    listRequest.HighRange = "200";
                    Google.Apis.Customsearch.v1.Data.Search search = listRequest.Fetch();

                    foreach (Google.Apis.Customsearch.v1.Data.Result result in search.Items)
                    {
                        Console.WriteLine("Title: {0}", result.Title);
                        Console.WriteLine("Link: {0}", result.Link);
                    }
----------------------------------------


But it doesn't make sense in this experiments.... or maybe due to the different search engine mirror used in my case...
