I did see the Search by City/Township entered by Jeff Karelius in early May.
I would like to see two exclusive sort (or search) options available publicly. One for zip and one for city.
It would be nice if those two options, used independently or together, would only provide those data records in the categories and subcategories.
The reasoning behind this request is I want people to find what they are looking for as close to them as possible. For example this would be similar to restaurants near me, but this search would be exclusive to the zip and or city and then only those records within the categories and subcategories.
The options would have to be optionally selectable by a site visitor and would only need to be matching the text the visitor provides in the field for that occurence of data display.
I am keying off the fact that you are already using a matching search function for the business name and tags as the main search and then assuming that two more matching search fields would inherently sort already.
