we have in our index fields with arrays, each containing only one element, which is NULL:
I would like to filter on just these records, however I can't find a query that will do this. ELS somehow does not like 'null' in this constellation.
Can anyone help?
Many thanks and greetings
null value cannot be indexed or searched, there is a
null_value parameter which allows you to replace explicit
null values with the specified value so that it can be indexed and searched.
Check out this documentation.
