I started typing "Morphia" in my browser's search box and it didn't answer that question, but as soon as I typed "Morphia agg" it suggested "Morphia aggregation example" as a possible search.

So the short answer to Arthur's question must be "Yes", since apparently a lot of people have searched the web for that exact question.

It turns out that Morphia is related to MongoDB so I'm going to add this thread to that forum.

Thanks, Arthur! It looks to me like baeldung.com is a pretty good source for tutorials.
