Query on array fields with null value

Hello all,

we have in our index fields with arrays, each containing only one element, which is NULL:

"field": [

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

Hi @dhggw!

While a 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.
