I have developed this logic myself, and I am currently using it as a demonstration of the ideal behavior we would like to achieve using Ajax Search Pro.
Please note that the provided URL does not represent a true search engine—it is a filtering mechanism where we have programmatically overridden the query results.
With that in mind, is there any possibility that Ajax Search Pro could support similar functionality? Alternatively, would you be able to suggest the best approach to overriding the plugin’s query logic to return results based on both the selected location and its neighboring areas?
Please let me know if any additional clarification is needed.
