Sorry, I wrote that at the end of a long day and totally confused my terms. I didn't mean profiles at all, I actually meant to say adverts. Here's what I was trying to say, but with the correct words:
"I need to add listings that don't actually have full advert pages, but will still appear in the search results. Is there any way of doing this? Or do all listings get their own advert, no matter how few fields are filled in? Is there a way to make this happen? Say, whenever a specific field is left empty then there is no advert."
So let's say for simplicity, that there's a field called "full-advert". If it says "yes" then when a search is done, that listing will be clickable and have its own page. But if it says "no" then the listing will appear in the search results but it won't be clickable and the person searching will not be able to get more details that what is in the search results page.
I hope that makes more sense this time! Apologies again
