Searching in a nested array

[Karl Hörnell]

Perhaps this belongs in the newbie forum. I couldn't find any documentation about a particular search case. Suppose I have a collection "scifi_lovers" of documents in this format:

{
"firstname":"John",
"lastname":"Smith",
"books":[
{"title":"Dune", "author":"Frank Herbert"},
{"title":"Fahrenheit 451". "author":"Ray Bradbury"}
]
}

How would I use X DevAPI to find documents where the "books" array contains a specific title?
