What I do in these case:
First of all: change the cardinality between DateSearch and User to many-to-many.
After your retrieve: link the found users to the DateSearch object.
Then show a page.
The page should have a data view for DateSearch. Within that data view, you can show a data grid with associated objects (associated users).
(This could also be the page your calling the microflow from. Make sure to ‘refresh on page’ when you link the results to the DateSearch)
