Filter expression to check if a string contains the column value

REST API
1

I am checking if a string contains the column value. For example, let us say, we have an org_id field. And there is a comma separated string of org_ids like: ,123,227,4,89,.

I want to write a filter query which does:
“,123,227,4,89,” contains “, + org_id + ,”

The above is not SQL but just a pseudocode. Hoping if DreamFactory filter has something for this.
