// submitSearch () - create the actual array from a given user search
//
// getFiltersCount() - returns the count of search filters (e.g. area, category, subcategoy == 3)
//
// createSearchDescription(dataarray) - takes the product of createSearchArray and constructs the link text
//
// createSearchLink(dataarray) - takes the product of createSearchArray and constructs the search link
//
// see mySearchExample.js
