anchor.diff:  == Sample route
   
   The following route defined in Spring XML executes the operation
  -xref:mongodb3-component.adoc[*dbStats*] on a collection.
  +<<getDbStats>> on a collection.
   
   *Get DB stats for specified collection*
   
  
positive.code: This operation retrieves only one element from the collection whose _id
  field matches the content of the IN message body. The incoming object
  can be anything that has an equivalent to a `Bson` type. See
  http://bsonspec.org/#/specification[http://bsonspec.org/#/specification]
  and
  http://www.mongodb.org/display/DOCS/Java+Types[http://www.mongodb.org/display/DOCS/Java+Types].
  
  
negative.code: matches a MongoDB query. *The query object is extracted `CamelMongoDbCriteria` header*.
  if the CamelMongoDbCriteria header is null the query object is extracted 
  message body, i.e. it should be of type `Bson` or convertible to
  `Bson`. It can be a JSON String or a Hashmap.
  See <<Type conversions>> for more info.
  You can use the Filters class from MongoDB Driver.
  
  Example with no query (returns any object of the collection):
