Portal_catalog search question

Is there a way to search the catalog if you have an 'unset item'?

I use:

 self.context.portal_catalog(portal_type='my type', cat_index1=my_index1, cat_index2=my_index2)

Which works if I have a value for both my_index1 and my_index2

But: Is there a way to search if my_index2 (or 1) is not set to some¨ specific value? ( is there some kind of 'wildcard' ?

my_index2 = '*'
my_index = None
my_index = []

If not: what is best

Search without the index, then filter or
Construct the search_query before doing the search

There is no way to search for unset values because most or all index types ignore indexable values evaluating to False or being None.

you can but not with just a query unfortunately.

Long time ago, in plain-Zope-days, you could query for None values using a tuple:

context.portal_catalog(your_index=(None,))
