Is it possible to be able to search for one or more specific datasets, rather than all contents of the site?
Also, is it possible to link an element to more than one dataset? I want to link a gallery to 3 datasets rather than just one.
Do you mean database collections when you refer to datasets ? Or, do you just want to do this by using datasets for data binding? You can also add code to query the database collections to retrieve the data you want.
Depending on your data, you can use a reference field . You can learn more from the Multiple References example.
Yes, I’m talking about a collection. I want one gallery to contain items from 3 different collections.
