Code sample

Go

To authenticate to Firestore, set up Application Default Credentials. For more information, see Set up authentication for a local development environment. 

// Note: This is an invalid query. It violates the constraint that range
// and order by are required to be on the same field.
query := cities.Where("population", ">", 2500000).OrderBy("country", firestore.Asc)

Java
