be added to the query, but those criteria come from the session

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

__dict__ attribute of an instance of SomeObjects (see in

instance: that way, it can be used in ZPTs without security problems.

useful for some usages like knowing the number of objects without

If p_noSecurity is True, it gets all the objects, even those that the

currently logged user can't see.

|
|
The result is sorted according to the potential sort key defined in
|
|
the Search instance (Search.sortBy). But if parameter p_sortBy is
|
|
given, it defines or overrides the sort. In this case, p_sortOrder
|
|
gives the order (*asc*ending or *desc*ending).
|
|
|
|
If p_filterKey is given, it represents an additional search parameter
|
|
to take into account: the corresponding search value is in
|
|
p_filterValue.
|

If p_refField is given, the query is limited to the objects that are

referenced through it.'''
