Django unrecognized token: "#" while query - django

Question

I simply want to implement a search view into my Django app. But when i try to search something on my App i get the following error:
'unrecognized token: "#"'
In the end i want that my Query is a combination of category and searchword. So that the user can filter specific categories (Just like Amazon.com searchfield) e.g.: http://127.0.0.1:8000/search/?category=1&q=hallo
base.html
...
<div class="globalsearch">
<form id="searchform" action="{% url 'search' %}" method="get" accept-charset="utf-8">
<label for="{{ categorysearch_form.category.id_for_label }}">In category: </label> {{ categorysearch_form.category }}
<input class="searchfield" id="searchbox" name="q" type="text" placeholder="Search for ...">
<button class="searchbutton" type="submit">
<i class="fa fa-search"></i>
</button>
</form>
</div>
</div>
...
categorysearch_form is a dropdown selector that gets his ID from the Database.
views.py
...
from django.contrib.postgres.search import SearchQuery, SearchRank, SearchVector

def get_queryset(self):

keywords = self.request.GET.get('q')

title_vector = SearchVector('title', weight='A')
content_vector = SearchVector('content', weight='B')
tag_vector = SearchVector('tag', weight='C')
vectors = title_vector + content_vector + tag_vector

qs = qs.annotate(rank=SearchRank(vectors, query)).order_by('-rank')
return qs

Search.html results are getting displayd here:

def __str__(self):

...
i guess im simply missing something
at that point...
I already read that this issue comes from local SQL database aka. SQLite, could that be true?
Smb. has a solution?
Thanks

After a bit of tinkering with a friend i found a solution, the Django Documentation according to vector searching is really not that good...
views.py
class globalsearch(ListView):
"""
Display a Post List page filtered by the search query.
"""
model = Post
paginate_by = 10
template_name = 'quickblog/search.html'
def get_queryset(self):
keywords = self.request.GET.get('q')
if keywords:
query = SearchQuery(keywords)
title_vector = SearchVector('title', weight='A')
content_vector = SearchVector('content', weight='B')
tag_vector = SearchVector('tag', weight='C')
vectors = title_vector + content_vector + tag_vector
qs = Post.objects.annotate(rank=SearchRank(vectors, query)).filter(rank__gte=0.1).order_by('-rank')
return qs
models.py

category = models.ForeignKey(Category, verbose_name="Category", on_delete=models.CASCADE, null=True)
postattachment = fields.FileField(upload_to='postattachment/%Y/%m/%d/', blank=True ,null=True)
