def $and[T](filters: Seq[T])(implicit writer: JsonWriter[T]): JsObject

$and performs a logical AND operation on an array of two or more expressions (e.g. expression1, expression2, etc.) and selects the documents that satisfy all the expressions in the array. The $and operator uses short-circuit evaluation. If the first expression (e.g. expression1) evaluates to false, MongoDB will not evaluate the remaining expressions.
