Thanks for your speedy response George. I have decided to go the parameter route:
I have clicked send additional parameters, input a key and included the input criteria as the parameter to include in the URL
Similarly, on the page I am sending the data to, in the repeating group I have done a search for the type of content I am displaying, and as a constraint, I have selected the criteria (field) = get ? parameter from URL
This isn’t working as when the search button is clicked on the first page, the results in the repeating group have not changed.
I imagine this is because the “key” doesn’t line up to the field in my repeating group?
