如何使用或运算符创建等同于SQL查询的Django查询集?

在Django,我知道使用 filter 多个参数转换成SQL AND 条款。从Django的书中:

可以将多个参数传递到 filter()缩小范围 进一步:

>>> Publisher.objects.filter(country="U.S.A.", state_province="CA")
[<Publisher: Apress>]

这些多重论点得到 转换为SQL和子句。因此, 代码段中的示例 转化为以下内容:

SELECT id, name, address, city, state_province, country, website
FROM books_publisher
WHERE country = 'U.S.A.'
AND state_province = 'CA';

如何创建转换为SQL的django查询集 OR 条款?例如:

SELECT id, name, address, city, state_province, country, website
FROM books_publisher
WHERE state_province = 'AZ'
OR state_province = 'CA';
