Answer 1

The following example demonstrates how to delete a single document with the name "Foo Bar" from a people collection in test database on localhost, it uses the Remove() method from the API:

// Get session
session, err := mgo.Dial("localhost")
if err != nil {
    fmt.Printf("dial fail %v
", err)
    os.Exit(1)
}
defer session.Close()

// Error check on every access
session.SetSafe(&mgo.Safe{})

// Get collection
collection := session.DB("test").C("people")

// Delete record
err = collection.Remove(bson.M{"name": "Foo Bar"})
if err != nil {
    fmt.Printf("remove fail %v
", err)
    os.Exit(1)
}
