Search function returning nothing -Django - django

Question

def Search(request):
if request.method == 'GET' and request.GET['x']:
parameter = request.GET['x']
results = Category.objects.filter(advert__Seller_Name__icontains = parameter)
return render(request, 'campusbuy/search.html', {'results': results})
else:
return render(request, 'campusbuy/search.html')
Above is my search function. When I try to search for an object in my template, it returns nothing. However, when I deliberately search for a Seller_name that's not in the db it returns the {% else %} value. Below is the template:
% extends 'campusbuy/base.html' %}
{% block content %}
{% if results %}
{% for ads in results.advert_set.all %}
<p>{{ads.Seller_Name }}</p>
<p>{{ads.Location}}</p>
<p>{{ads.Description}}</p>
<p>{{ads.Asking_Price}}</p>
{% endfor %}
{% else %}
<p>No Ad matched your search criteria.</p>
{% endif %}
{% endblock %}
Here's the models.py:
class Category(models.Model):
Name = models.CharField(max_length=20, null=True, blank=True)
Details = models.CharField(max_length=100, default="Default")
Category_Logo = models.ImageField(max_length=100, upload_to='uploads')
def __str__(self):
return self.Name
class Advert(models.Model):
HALL3 = 'HALL3'
HALL4 = 'HALL4'
HALL2 = 'HALL2'
MAIN_GATE = 'MAINGATE'
HALL1 = 'HALL1'
Location_Choices = (
(HALL3, 'Hall3'),
(HALL4, 'Hall4'),
(HALL2, 'Hall2'),
(MAIN_GATE, 'Main_gate'),
(HALL1, 'Hall1')
)
category = models.ForeignKey(Category, on_delete=models.CASCADE)
Seller_Name = models.CharField(max_length=50, blank=False, null=False)
Phone_Number = models.CharField(max_length=11, blank=False, null=False,
help_text='<p style="color: red; font: italic 12px tahoma;">**Please input a working Phone Number that you can be contacted with on the fly</p>')
image = models.ImageField(max_length=100, upload_to='uploads')
Item = models.CharField(max_length=20, blank=False, null=False)
Location = models.CharField(max_length=10, choices=Location_Choices, default=HALL3, blank=False)
Description = models.TextField(max_length=250, blank=False, null=False)
Asking_Price = models.CharField(max_length=20, blank=False, null=False)
published_date = models.DateTimeField(blank=False, default=timezone.now)
Thank you in advance!

I still haven't understood why you've tried to include Category in the query, since you are not using it at all either in the query itself or in the template. Just query and use Adverts directly:
results = Advert.objects.filter(Seller_Name__icontains=parameter)
and iterate over it also directly:
{% for ads in results %}
<p>{{ads.Seller_Name }}</p>
<p>{{ads.Location}}</p>
<p>{{ads.Description}}</p>
<p>{{ads.Asking_Price}}</p>
{% endfor %}
Also note, you don't need the if block, because the for template tag has an [empty`](https://docs.djangoproject.com/en/2.1/ref/templates/builtins/#for-empty) clause that is displayed if the loop was empty:
{% for ads in results %}
<p>{{ads.Seller_Name }}</p>
<p>{{ads.Location}}</p>
<p>{{ads.Description}}</p>
<p>{{ads.Asking_Price}}</p>
{% empty %}
<p>No Ad matched your search criteria.</p>
{% endfor %}
