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