FeinCMS：简单搜索

Question

我正在尝试构建一个简单的搜索我的feinCMS页面。 在this tutorial的帮助下，我创建了一个搜索所有页面标题的搜索：

def get_results(query_string, search_fields):
    ''' Returns a query, that is a combination of Q objects. That combination
        aims to search keywords within a model by testing the given search fields.

    '''
    if len(query_string)>1:
        results = []
        query = None # Query to search for every search term        
        terms = normalize_query(query_string)
        for term in terms:
            results += Page.objects.filter(title__contains = term)
        return results

但我不知道如何在各种内容类型中搜索。

现在我添加了markdowncontent_set = Page.content_type_for(MarkdownContent)但是我收到了什么？我如何循环浏览内容并检查它是否包含query_sring？

修改

现在我的代码看起来像这样：

def get_results(query_string, search_fields):
    ''' Returns a query, that is a combination of Q objects. That combination
        aims to search keywords within a model by testing the given search fields.

    '''
    if len(query_string)>0:
        results = []
        query = None # Query to search for every search term        
        terms = normalize_query(query_string)
        for term in terms:
            results += Page.objects.filter(title__contains = term)
            results += Page.objects.select_related("markdowncontent_set").filter(markdowncontent_set__content__contains = term)
        return list(set(results))

也许不是最好的解决方案，但它有效。
