If you are talking about dynamic restrictions then you could do:

var query = _session.QueryOver<Something>();
if(someterm!=null)
   query.Where(x=>x.SomeTerm==someTerm);

if(someotherterm!=null)
   query.Where(x=>x.SomeOtherTerm==someotherterm);

var results = query.List();

You could even join dynamically if you need to like:

if(something!=null){
  SomeReference srAlias = null;
  query.JoinAlias(x=>x.SomeReference,()=>srAlias, JoinType.LeftOuterJoin)
       .Where(x=>srAlias.Something==something);
}
