[storm] Storm : Multiple fields request

[Gerdus van Zyl]

Some code that I use to do the same thing:

cls = Employee
param = { 'age':30,'lastname':'smith' }

expressions = []
for k in param:
    v = param[k]
    if v == "none":
        v = None
    if hasattr(cls,k):
        expressions += [ getattr(cls,k) == v ]


sl = store.find(cls,And(*expressions))
