Alter search field

hello, my select2 component is working, it brings all consumers, but I would like to know if I can filter these consumers according to the logged in user. How to change a query?

Here’s my form code.

class ConsumidorWidget(s2forms.ModelSelect2Widget):
    search_fields = [

class ConsumoForm(forms.ModelForm):
    class Meta:
        model = Consumo
        fields = ('id', 'consumidor', 'mesconsumo', 'anoconsumo', 'valorapagar', 'valorhidrometro',
                  'dataleitura', 'datamissao', 'datavencimento', 'foipago',)

        exclude = ('bairro',)
        mesconsumo = forms.ChoiceField()
        # widgets = {
        #    'data_pagamento': DateInput(),
        # }
        widgets = {
            "consumidor": ConsumidorWidget,
