I was thinking about it and for a complete option to be able to express
all, what propositional logic allows, it should be enough so that we will add
NOT IN and NOT LIKE operators. All operators should have a positive and
negative form then every conditions can be transfomed to allowed constructions.
The next point is that I have forgoten on the fluent api for queries where
the operators have to impletented, too.
Do you agree with this solution?
