我在 comp.text.tex 上发布了完全相同的问题
我不知道我是否遗漏了什么,但我认为 biblatex 的以下功能非常棒:Biblatex 提供了定义所谓的参考书目过滤器的可能性。
有没有办法使用类似这样的语法来组合过滤器:
\defbibfilter{myNewFilter}{filter=AnOldFilter and not ( filter=AnotherFilter )}
?[一个更简单的建议] 有没有办法这样说:
\printbibliography[notfilter=MyFilter]
?我知道\printbibliography[filter=...]
并且\printbibliography[nottype=...]
存在,我想知道是否可以实现“notfilter”选项。
答案1
目前尚未实现过滤器组合。要组合过滤器,您必须创建自己的算法。
我想提出一种方法。因此我定义了命令:
\combinetwobibfilter{Arg 1}{Arg 2}{Arg 3}
带有三个强制参数。第一个参数是新过滤器的名称。第二个和第三个参数是两个预定义过滤器的名称。到目前为止,我还没有实施测试来检查过滤器是否已定义。

\printbibliography[title={No filter}]
\printbibliography[title={Filter One},filter=FilterOne]

\printbibliography[title={Filter Four=combination of filter two and filter three},filter=FilterFour]

结果是:
