CMIS predicate for unset property when searching in SOLR?
When I perform a database search using CMIS, I can check if a certain property has been set or has a null value using IS NULL, i.e.
cm:myProperty IS NULL
This finds a number of nodes where the property is never initialized or has been explicitly set to null. However, when I point the same query to SOLR, it finds nothing. The data should have been indexed succesfully, so it seems I need to express my query in some other way. With AFTS I can check if the value has been set to anything with the negation of EXISTS, i.e.
However, I'd rather not use AFTS. Is there any way to make this work with CMIS?
