{% for key, value in output %}
   {{ key }} <br>
    {% for key2 in value %}

To start with, your render function isn't accepting the correct arguments and that is why nothing is appearing on your html template. You typed this: 

return render(request, 'notebook/instant_search.html', output)

The correct one: 

return render(request, 'notebook/instant_search.html', 'output':output)

The above will solve the problem of template not displaying data from the render function.

Next is the code that will iterate through the dictionary:

The following will display each item in the list

{% for k, v in output.items %}
    {% for i in v %}
        {{ i }}
    {% endfor %}
{% endfor %}

while the code below will display each list

{% for k, v in output.items %}
    {{ v }}
{% endfor %}

return render(request, 'notebook/instant_search.html', {"output":output})

Change this statement in the views file and then you will get the output by having

<table>
{% for key, value in output.items %}
<tr>
<td>{{key}}</td>
<td>{{value}}<td> <!-- you can also run for on values list -->
</tr>
{% endfor %}
</table>

you can iterate dictionary directly in the template:

<table>
{% for key, value in my_dict.items %}
    <tr>
        <td>{{key}}</td>
        <td>{{value}}<td> <!-- you can also run for on values list -->
    </tr>
{% endfor %}
</table>

hope it helps
