Passing 3 user inputs as argument in url, for a search form

I am building a search form where the user inputs 3 values on a form, and I search the database for all records that match the 3 inputs.  Right now I am stuck on the user input part.

If you look at my urls.py, you will see that I tried to put 3 keywords arguments in there.  Then I tried to pass the 3 keyword arguments in the url tag with variables from my forms.py.  I think this is where things went wrong but I'm not sure.  I don't know if the .html file can use variables from forms.py

Basically what I'm trying to do is to take the 3 user inputs, and pass them as arguments in the URL.  Right now I'm getting:

NoReverseMatch at /

Reverse for 'search-results' with keyword arguments '{'pt': '', 'nb': '', 'nw': ''}' not found. 1 pattern(s) tried: ['search?(?P<pt>\\w+)&(?P<nb>\\w+)&(?P<nw>\\w+)']

urls.py

url(r'^search?(?P<pt>\w+)&(?P<nb>\w+)&(?P<nw>\w+)', views.IndexSearchResults.as_view(), name='search-results')

index.html 

<form action="{% url 'search-results' pt=property_type nb=number_of_bedrooms nw=number_of_washrooms %}" method="get">

    {{ form.as_p }}

</form>

views.py

class IndexSearchResults(generic.ListView):

    template_name = 'search-results.html'

models.py

Class BuyerListing(models.Model):

     BEDS_OPTION = (

        (BEDS_0, '0 [Studio/Bachelor]'),

        (BEDS_1, '1'),

        (BEDS_2, '2'),

        (BEDS_2_1, '2+1'),

        (DETACHED_HOUSE, 'Detached House'),

        (SEMI_DETACHED, 'Semi-detached'),

        (TOWNHOUSE, 'Townhouse'),

    )

    property_type = models.CharField(max_length=50)

    number_of_bedrooms = models.CharField(max_length=50, default=BEDS_0)

    number_of_washrooms = models.CharField(max_length=50, default=WASH_1)

forms.py

class MainSearch(forms.Form):

    property_type = forms.ChoiceField(choices=BuyerListing.PROPERTY_TYPE)

    

    number_of_bedrooms = forms.ChoiceField(choices=BuyerListing.BEDS_OPTION)

    

    number_of_washrooms = forms.ChoiceField(choices=BuyerListing.WASH_OPTION)
