Ï think you'll have to create your own "ToLowerParameter" extension method
and use that instead of ToLower. Mark the method with
[LinqExtensionMethod("lower")]
"Since NHibernate v5.0, the Linq provider will no more evaluate in-memory
the method call even when it does not depend on the queried data."
In other words, it will be converted into a SQL call.
