will be added to the query, or;
2) "_advanced": in this case, additional search criteria will also

We will retrieve objects from p_startNumber. If p_search is defined,
it corresponds to a custom Search instance (instead of a predefined
named search like in p_searchName). If both p_searchName and p_search
are given, p_search is ignored.
This method returns a list of objects in the form of the
__dict__ attribute of an instance of SomeObjects (see in
appy.gen.utils). We return the __dict__ attribute instead of real
instance: that way, it can be used in ZPTs without security problems.
If p_brainsOnly is True, it returns a list of brains instead (can be
useful for some usages like knowing the number of objects without
needing to get information about them). If no p_maxResults is
specified, the method returns maximum
