问题：imakeidx我正在使用、biblatex和Xindy创建作者、标题和主题索引indexing=true。索引创建正确，但标题索引包含我不想要的斜体条目。我从以下答案中找到了代码莫威和曼纽尔茨以适应我的文件需求。
我已尝试过：我尝试\emph用另一个\emph类似方法否定：
\DeclareIndexFieldFormat{indextitle}{%
\usebibmacro{index:title}{\index[titles]}{\emph #1}}
但使用它（在我的主文件中）的结果并不一致：
我想要的是：文件中\emph写入的命令首先被否定或不插入。如果知道是什么过程导致添加，那就太好了，因为我看不出它来自哪里。\itemtitles.ind\emph

目前的情况：
标题索引目前如下所示：
titles.ind生成的文件包含以下内容：
\begin{theindex}
\providecommand*\lettergroupDefault[1]{}
\providecommand*\lettergroup[1]{%
\par\textbf{\large#1}\par\medskip
\nopagebreak
}
\lettergroup{G}
\item \emph {Gromov invariants for holomorphic maps on {Riemann} surfaces}\dotfill \hyperpage{1}, \hyperpage{2}
\indexspace
\lettergroup{H}
\item \emph {Hemingway's Style and {Jake's} Narration}\dotfill \hyperpage{1}, \hyperpage{2}
\item \emph {Herder and the Preparation of {Goethe's} Idea of World Literature}\dotfill \hyperpage{1}, \hyperpage{2}
\indexspace
\lettergroup{P}
\item \emph {Partial Symmetries of Weak Interactions}\dotfill \hyperpage{1}, \hyperpage{2}
\end{theindex}
我将非常感激任何关于如何删除强调的建议，我无法弄清楚是什么函数或过程导致将\emph添加到titles.ind文件中。如果这个问题之前已经问过，我很抱歉，经过一番搜索，我还是找不到答案。我确信我对 Xindy 和 的使用是错误的arara，makeindex但它编译正确，所以一定没问题。
答案1
看来我的
相当不错的搜索
还不够。从biblatex.def文件在 GitHub 上找到，第 1185-1194 行，索引命令已找到，问题出在这行代码上：
\newbibmacro*{index:title}[2]{%
\usebibmacro{index:field}{#1}{\thefield{indexsorttitle}}{\emph{#2}}}
\emph如果需要删除，应按如下方式编辑：
\renewbibmacro*{index:title}[2]{%
\usebibmacro{index:field}{#1}{\thefield{indexsorttitle}}{#2}}
新文件将根据需要产生以下输出：
