How do You solve Part 3?

Can't figure out how to solve part 3 in the method queryset. I'm stuck on how you use the filter by queryset.filter().

from django.contrib import admin

from . import models

class TextInline(admin.StackedInline):
    model = models.Text

class QuizInline(admin.StackedInline):
    model = models.Quiz

class AnswerInline(admin.StackedInline):
    model = models.Answer

class TopicListFilter(admin.SimpleListFilter):
    title = 'topic'
    parameter_name = 'topic'

    def lookups(self, request, model_admin):
        return (("Python", "Python"), ("Ruby", "Ruby"), ("Java", "Java"))

    def queryset(self, request, queryset):
        if self.value():
            return queryset.filter(self.title)

class CourseAdmin(admin.ModelAdmin):
    inlines = [TextInline, QuizInline]

    list_filter = ['created_at', 'is_live']

admin.site.register(models.Course, CourseAdmin)

Forget the question I solved it. You use title__contains=self.value().

        def queryset(self, request, queryset):
        if self.value():
            return queryset.filter(title__contains=self.value())
