I am working on a new website/directory using Wordpress and require a search functionality that will let me search using 2 input fields. I'm not sure if i have explained this correctly so here is a screenshot to show what i am trying to achieve... it will require the user to input what they are looking for and where. Is this possible to do in wordpress?

I have spent a couple of hours looking around the internet to see how i could do this but haven't found anything yet. Does anyone know how i could do this using the built in WordPress search or a plugin?

Thanks
