You can probably create a custom filter and do something like this:

from django.db.models import Q
import django_filters


class LocationFilter(django_filters.FilterSet):
    q = django_filters.CharFilter(method='my_custom_filter', label="Search")

    class Meta:
        model = Location
        fields = ['q']

    def my_custom_filter(self, queryset, name, value):
        return queryset.filter(
            Q(loc__icontains=value) |
            Q(loc_mansioned__icontains=value) | 
            Q(loc_country__icontains=value) | 
            Q(loc_modern__icontains=value)
        )

This would filter by any of of those fields. You can replace the icontains with whatever you want.

This is perfect. I’m trying to do a dynamic filter, with a switch to get one more field in the search if checked. Something like this:

def my_custom_filter(self, queryset, name, value):
    return Reference.objects.filter(
        Q(ref_title__icontains=value))

def my_custom_filter_with_description(self, queryset, name, value):
    return Reference.objects.filter(
        Q(ref_title__icontains=value) | Q(complete_description__icontains=value))

But I have no clue how to link the switch to the class

Due that you’ve defined Location as an object, to filter by multiple fields just use the filter method.

filterlocation = Location.objects.filter(loc=formloc, loc_mansioned=formlocmansioned, loc_country=formloccountry, loc_modern=formlocmodern)

But you need to implement a better way to use this filters, so only the result that have all conditions will be displayed.

Another solution, since the other one was not working directly:

@staticmethod
def filter_stock(qs, name, value):
    return qs.filter(
        Q(ticker__exact=value) | Q(company__iexact=value)
    )
