When I use the above, and for example search the following:-
http://46.101.2.132/jobs/?s=Buying
It now loads a different page template, it needs to search the archive only, I don’t know if this makes it any different.
Usually the template loads as follows:-
http://46.101.2.132/jobs/?job_sector=&job_salary_from=&job_type=&job_location=
