By default, display table empty unless a filter on the data returns matches ... How do I do it?

Greetings, I want to ask you about a behavior that they asked me exclusively to achieve with the DataTables that I do not find how to achieve it.
In my scenario, I retrieve data from a server (node ​​js) that returns data in json format and I have it paged from the DataTables configuration.
But I was asked that the default listing does not show any rows unless a filter is written that has matching results. How I do this?

I'm not sure, but is it possible that the datatables have already downloaded all the records before showing them?

My Config tiene:
bLengthChange: true,
lengthMenu: [[5, 10, 25, 50, -1], [5, 10, 25, 50, "Todas"]],
pagingType: "first_last_numbers",
pageLength: 5,
data: dataSet,
ajax: "/reservas/json/",
sAjaxDataProp: "datos.reservas",
