Question

In the MongoDB Documentation we’ve got the following example:

db.factories.insert( { name: "xyz", metro: { city: "New York", state: "NY" } } );
db.factories.ensureIndex( { metro : 1 } );
// this query can use the above index:
db.factories.find( { metro: { city: "New York", state: "NY" } } );

I’m currently looking for a solution to archieve this query in spring data. My first approach was

Query.query(Criteria.where("metro")
    .andOperator(Criteria.where("city").is("New York")
    .and("state").is("NY")))

but this results in the following query

{ "metro" : { } , "$and" : [ { "city" : "New York" , "state" : "NY"}]}

Answer 1

Finally i found the solution by fiddling around:

Query.query(Criteria.where("metro").is(
    Query.query(
        Criteria.where("city").is("New York")
        .and("state").is("NY")).getQueryObject()
    )
)
// results in { metro: { city: "New York", state: "NY" } }

Hopefully this is the right way to do it…
