URL variable search
Does anybody know if it is possible to edit the url variable before it is passed to the job search?
What I currently have is the following:
If you search for php developer roles, the url submitted is sitename/?s=php+developer, the url is displayed as sitename/search/php+developer
What would be great is if I could have 'sitename/php-jobs-in-birmingham' for example - when the search is performed I would like to edit ?s=php-jobs-in-birmingham (which would return nothing) so that the -jobs-in- element is replaced with a + before searching so the search is actually only for 'PHP+Birmingham'.
This would allow urls similar to indeed -
http://www.indeed.co.uk/PHP-jobs-in-Birmingham.
I can get all of the heading etc to do this but can't find where this variable is passed to the search.
Any help would be great.
Thanks
