jsonArrayContains Search Operator
Use the jsonArrayContains operator to determine whether a JSON array contains a particular item.
Syntax
jsonArrayContains(<jsonArrayField>, <stringField>)
The <jsonArrayField> argument is a field that contains a string in JSON array format (for example, ["foo", "bar"]). <stringField> is a string to check against the items of that array (for example, "foo"). If the item is in the array, it returns true; otherwise it returns false.
