Is there anything else?

Yeah.

I mean, I think one of the key things from the contributions on realist searching that I did with colleagues in Leeds and Exeter, that we tried to break the search process down into a number of different stages with different purposes.

And so again, I think it's very important to not think of these as solutions for all the requirements of the realist, but to think of what tools do you need for each stage.

So yes, that initial exploration that we talked about, program theory, surfacing that, then these tools that I've already mentioned can be useful.

Later on, when it comes to theory testing, then you find that, well, two main characteristics.

One is that very often you're trying to dive into the contents of articles rather than through, if you like, the shop window of the titles and abstracts.

So looking into the future, where do you think this is going?
