back when I was a student, I would sometimes spend hours on Ryanair's website to find that type of deals.
My base was Paris and I wanted to go to Stockholm for example. The direct Ryanair flight from Paris to Stockholm was expensive (Let's say 150 euros).
I would manage to find two cheap flights that go for example from Paris to Rome and another one from Rome to Stockholm, both of those for 10 Euros each. The key is to use the big Ryanair hubs as gateway (Milan and Brussels would work really well back in the days)
I would basically lose my whole day traveling to save 80 euros.
Sometimes it backfires though, and when it backfires you are on your own. Once my first flight got super delayed, and I got stuck in Milan for the night. I managed to have Ryanair rebook my second flight for the day.
I think Ryanair wants to be able to propose high prices for direct flights and prevent people from finding those cheaper indirect flights. That's why they don't make it easy to find them.
Most comparison sites will show you these routes, for example Kiwi lets me search indirect flights from where I am in a remote part of Spain to where I live the other side of Europe. There's no direct routes, but it gives me the option of connecting in Barcelona, Stansted or Hahn, or cheaper options if I want more that one stop. It also lets me search a whole month to find the cheapest flights in a given time period, and will provide options with different low-cost airlines if that's cheaper.
However if you book direct through these sites you are going to get the lowest ticketing class. With Ryanair that means you can't take anything more than a small bag onboard (since November you need to pay for a 10kg cabin bag, you can't drop it at the gate for free), and if you are in a group you will not be sitting next to each other, so it may be best to book directly through the airline's site.
The simple reason why Ryanair don't let you book multi-leg flights directly is because they don't want to be responsible for you missing a connection. It's ironic though, as compared to national European airlines I find their punctuality a lot better.
There are several other reasons for not wanting to handle connections, including complexity of IT systems, negotiations with airports (bag transfer is more complicated), and general airline processes. I imagine they will end up doing it, Easyjet have started to act as feeders for global airlines - it's a clever idea
