How to avoid "0 Search Results Found" - I want to link to a product when no results are found

I’m in the process of finishing up my online store. It will specialize in map posters. I have added over 50 locations for the map prints but I am also offering a customisation service for locations that I don’t have on the store. Therefore, I was wondering if it is possible to recommend my custom design map print listing when the search bar shows no results.

For example, if someone was to search for a Paris Map Print. This is not a print I currently stock. However, I would like to direct them to my customisation page which is - https://saltwaterprints.co.uk/products/create-your-own-any-location-any-country

My website can be accessed at - https://saltwaterprints.co.uk

I’ve looked for shopify apps to solve this issue but can’t seem to find any that would do the job.

I’d really appreciate any help I can get with regards adjusting code or whatever is necessary to achieve this.

(My shop theme is Debut)

Thanks so much,

Matthew
