Setting up a new project to evaluate what you've got going on here and ran into a bug fairly early on. After going through the quickstart and tutorials, I moved on to using the api and ran into the following error:

AssertionError at /api/vectordb/search/

AutoFilterSet resolved field 'metadata' with 'exact' lookup to an unrecognized field type JSONField. Try adding an override to 'Meta.filter_overrides'. See: https://django-filter.readthedocs.io/en/main/ref/filterset.html#customise-filter-generation-with-filter-overrides

Note, I was able to work around this issue by editing the vectordb/views.py file from

class VectorViewSet(viewsets.ModelViewSet):
    queryset = Vector.objects.all()
    serializer_class = VectorSerializer
    filter_backends = [DjangoFilterBackend, filters.SearchFilter]
    filterset_fields = ["text", "metadata"]
    search_fields = ["text", "metadata"]

to 

class VectorViewSet(viewsets.ModelViewSet):
    queryset = Vector.objects.all()
    serializer_class = VectorSerializer
    filter_backends = [DjangoFilterBackend, filters.SearchFilter]
    filterset_fields = ["text"]
    search_fields = ["text", "metadata"]

i.e. just removing the metadata field from the filterset_fields.

Very nice project otherwise though!
