Search filter

Hey,

How do I use a shortcode like [gd_advanced_search]

and add some filters to only search within a defined tag?

To better explain, I would like to place the search bar via shortcode on a specific page and have the search results ONLY return items that are from a/set of specific “tags”.

So if a user searched ‘coffee’ it would only return listings that contained ‘coffee’ AND had the specific tag.

Thank you.
