Search with Pagignation

Hi,

I am trying to make a search with pagignation . And i already make it . But pagignation its not working properly. For pagignation i follow this tutorial :https://ellislab.com/codeigniter/user-guide/libraries/pagination.html

If i in second page (with pagignation ) and then try to back in 1st page (by clicking pagignation number) . Then its shows me all result again . Also url is showing /10 . I think url need to show this with my search query . So, in future anyone can use this url.

I am new with codeigniter. And search lot in google . Please any help will highly appreciate.

Best Regards
