[Zope3-dev] RFC: should z.a.c.attribute.AttributeIndex index None values?

[Adam Groszer]

Hello,

Solutions:

a: No, do not keep None values in the catalog
   the current implementation works like this
   you are unable to ask the catalog for objects having None
   properties
b: Yes, keep None values in the catalog
   you can ask the catalog for objects having None properties
c: Let's keep the existing one that does not index None and have an
   AttributeIndexAlsoNone class which will index None values
