Search box renders just part of the results

Hi, in https://hispanicla.com I am using the search box (search template – tagdiv) for the authors (around 300) and their followers to look for their posts. I am using the latest update of Newspaper.
But when I imput the name of any author I only receive a fraction of the posts they authored. Actually most posts do not appear in the result.
I tried importing the search template from Magazine Pro using the Cloud Templates but I got the same result (in a very nice page, etc.).
Is there a way to get all the results?
Thank you!

Thank you, Vlad. But that is exactly what I am using in the front page https://hispanicla.com, the Search Box you pointed to.
The problem is again that only few entries are shown for the author when we imput the name in that box. For example, author “Gabriel Lerner” has 355 posts under his name, yet only 84 appear. Author “Nestor Fantini” has 92 authored yet just 49 appear. And so on. Thanks!
