How Pagination Works
By default the software will show 50 results on the first page. You can use the forward and back buttons to go either to the next page of results or the last and the first page results.
Example
The results above are having 74 results and that's why the software is showing pages as "2".
Example
You can decide if you want to view only 50 , 25 or 10 pages of results at a time and that way the number of pages will also get adjusted.
