The common ones are, but not all of them (at least, I don’t think so).
Note, you can also write (avoiding all the nested Or restrictions):
session.QueryOver<MyType>()
.Where(Restrictions.Disjunction()
.Add(Restrictions.On<MyType>(t => t.Field1).IsNull)
.Add(Restrictions.On<MyType>(t => t.Field2).IsNull)
.Add(Restrictions.On<MyType>(t => t.Field3).IsNull));

Yes

Yes ...
http://nhforge.org/doc/nh/en/index.html#queryqueryover-additionalrestrictions
... but it looks like there’s nothing on the extensions. I’ll see about adding
some.

Hmm, what is this '.IsNull()' business? Extension methods on object/string?
Are all Restriction methods available this way, i.e. IsLike, IsBetween, etc.
Will this still work when using aliases? (i.e. 'JoinAlias').
Thanks for this info Fabio, looks interesting, is there any docs describing
this stuff?
