\printindex
\printbibliography
\end{document}

结果是这样的： 索引和参考书目

索引有点混乱，因为一些作者的名字被识别为›符号‹，因为 biblatex archaeologie-optioninitials激活了自动获取作者姓名首字母的可能性，如 @ienissei 所述https://tex.stackexchange.com/a/295486/98739。

@moewe 发现这是因为还考虑了姓氏：

\indexentry{{Fr}ost, {\relax {}Fr}ank|hyperpage}{1}
\indexentry{{Kr}ause, {\relax {}Cl}emens|hyperpage}{1}
\indexentry{{Gr}aefe, Rainer|hyperpage}{1}

有没有办法只考虑名字？或者我怎样才能省略{}姓氏中的？

答案1

一个暂定的解决方案，假设您使用的<von> <last>, <suffix>, <first>名称格式：

\DeclareStyleSourcemap{%
  \maps[datatype=bibtex]{%
    \map{%
      \step[fieldsource=author,%
        match={\regexp{([^,]\s)(Chr|Ch|Th|Ph|[B-DF-HJ-NP-TV-XZ](l|r))}},%
        replace={\regexp{$1\{$2\}}}]% Protect last names (last, first)
      \step[fieldsource=author,%
        match={\regexp{([^\{])(Chr|Ch|Th|Ph|[B-DF-HJ-NP-TV-XZ](l|r))([^\}])}},%
        replace={\regexp{$1\{\\relax\{\}$2\}$4}}]% Insert \relax after abbreviating
}}}%

如果您将它添加到序言中，它有望发挥作用（尚未用 测试过imakeidx。至少它改进了 中的代码，.bbx现在内容如下：

... {Krause}{K\bibinitperiod}{{\relax{}Cl}emens}{{\relax{}Cl}\bibinitperiod} ...

但是，我不知道如何使其与<first> <last>名称格式一起工作，无论如何这都不是很流行（我猜）。
