Found sets can be created by using script steps like 'Perform Find', 'Extend Found Set' etc.
This works fine with a single value in a search field (i.e. UUID). The search function does not accept multi-line input.
The standard solution for this task is looping through the multi-line list and do an 'Extend Found Set' for each individual value.
However, this looping and extending can take some time when the list contains many values.
Working with a portal that uses the multi-line list as a predicate is not always possible.
What other methods do you employ for the task?
