Confluent filter condition not just one field but all fields in the topic

Hello, we have a problem with connect-transforms (connect-transformations | Confluent Hub)
I would like to filter out records containing a substring.
This substring can be at any field in the topic.
How can i use filter to look not just one field but all of them
“transforms.filterRecords.filter.condition”: “$[?(@.ALL THE FIELDS =~ /.searching_this_data./)]”,

thanks Carlos
