The Search parameter is a plain text search variable which will be used to filter against title and description data

Postcode searches allow us to perform a radial search of an area, sometimes we use postcode searches for a town or city, which allows us to include items that are near the center of the search postcode, but not too far, otherwise this would be considered a State or Region search

Distance is a search parameter which allows you to filter product results. If you wish to disable a certain parameter you simply need to click the cross next to the parameter.

Category restricts your search results to items that are set to this category and sub-categories of this category.
