Maximum

The Max method can be chained to a query to update the value of a field if the new value is greater than the current value.

Usage

result := WitcherModel.Where("name", "Vesemir").Max("age", 201).Exec().(*mongo.UpdateResult)

In the example above, we are updating the age of the witcher named Vesemir to 201 if the current age is less than 201.
