URL Filter Customization - Can you limit Search by Bounding Box?

[oconnor77]

For the URL Filter Customization feature described on this page
https://github.com/Esri/geoportal-server/wiki/Url-filter-customization

Is it possible to limit users search results to a specific geographic area based on an intersecting bounding box?

I've tried a number of different options to structure the URL but the syntax is alluding me and I wanted to confirm that this capability actually does exist and request a sample URL if anyone has one.

Thanks,
Sarah
