Changing position of the header in a view I have the "Result summary" in the Header for my view however, it is being displayed at the top of the content. I would like it to be displayed in between the search form and the search results. 
I would like a detailed answer, since I am new to Drupal (8) - I have seen an answer about how to change the position of the header (or footer) using a template.

I can't obviously change it using the admin UI. 

I am using Drupal 8.

Thanks!
In your custom theme check if there is a templates/views-view.html.twig file 

If not you you can get a copy from core/themes/stable/templates/views/views-view.html.twig and modify the position of header section to be below exposed 

the content should look similar to the following after your change

...
{{ exposed }}
{% if header %}
  &lt;header&gt;
    {{ header }}
  &lt;/header&gt;
{% endif %}
...


This will customize all views in your current installation

If you want to only modify a specific view you can name the file templates/views-view--VIEWNAME.html.twig

Here is more info on the template naming convention
