Information retrieval system (movies query)

In order to rate movies, the user needs to search for them using the home page:

By Typing some relevant words in the text box, the page will call (through the urls.py corresponding home URL) the home function in the views.py file:

def home(request):
    context={}
    if request.method == 'POST':
        post_data = request.POST
        data = {}
        data = post_data.get('data', None)
        if data:
            return redirect('%s?%s' % (reverse('books_recsys_app.views.home'),
                                urllib.urlencode({'q': data})))
    elif request.method == 'GET':
        get_data = request.GET
        data = get_data.get('q',None)
        titles = cache.get('titles')
        if titles==None:
            print 'load data...'
            texts = []
            mobjs = MovieData.objects.all()
            ndim = mobjs[0].ndim
            matr = np.empty([1,ndim])
            titles_list = []
            cnt=0
            for obj in mobjs...
