在这里，我给出了使用索引制作英语-阿拉伯语词典的问题的答案，用于一本概率书，感谢这个非常有力的讨论...... 使用 polyglossia 中的 multiind 包在从右到左和从左到右之间切换两列
这个想法是按照阿拉伯语顺序和英语顺序对条目进行排序，然后，根据命令\RTLdblcol（从右到左双列）\LTRdblcol...我们获得了包含阿拉伯语和英语条目的两本词典...
我给出这个例子是为了观察当索引的条目太长时会发生什么（使用文件中的包）...

并且，从现在起，“最大似然估计”条目太长了，为了获得更漂亮的条目，我手工处理了“dico-ar.ind”和“dico-eng.ind”排列的条目，并替换了条目
\item \idxsechead{مقدر الاحتمال الأعظم\hfill \LR {Maximum likelihood estimate}},
\idxnopage{1}
和
\item \idxsechead{Maximum likelihood estimate\hfill \selectlanguage {arabic}\RL {مقدر الاحتمال الأعظم}\selectlanguage {english}},
\idxnopage{1}
分别
\item \idxsechead{\begin{tabular}{b{3.5cm}b{2.5cm}}\LR{Maximum likelihood estimate}&\selectlanguage{arabic} %%% English index
مقدر الاحتمال الأعظم
\selectlanguage{english}
\end{tabular}\hrule\vspace*{5pt}},
\idxnopage{1}
\item \idxsechead{\begin{tabular}{m{3.5cm}m{2.5cm}} %%% Arabic index
\selectlanguage{arabic}
مقدر الاحتمال الأعظم
&
\selectlanguage{english}Maximum likelihood estimate
\end{tabular}\hrule\vspace*{1pt}},
\idxnopage{1}
当我们重新编译文件时，我们获得了更可接受的条目......
因此，我尝试制作一个宏来自动执行此操作...当我执行该命令并按照我为示例所做的操作时，我获得了该命令
\def\aeindex#1#2#3#4{%
\index{dico-eng}{#3@\string\idxsechead{\begin{tabular}{b{3.5cm}b{2.5cm}}\selectlanguage{english}\LR{#4}&\RLarabic{#2}\end{tabular}
\hrule\vspace*{5pt}}|idxnopage}%
\index{dico-ar}{#1@\string\idxsechead{\begin{tabular}{m{3.5cm}m{2.5cm}} \selectlanguage{arabic}\RLarabic{#2}&\selectlanguage{english}\LR{#4}\end{tabular}\hrule\vspace*{5pt}}|idxnopage}%
}% End of \aeindex...
但是，在编译时，我收到了错误消息（针对每个条目），我完全不明白。
! Argument of \reserved@a has an extra }.
<inserted text>
\par
l.85 ...{Multiplication rule}{Multiplication rule}
I've run across a `}' that doesn't seem to match anything.....
有人能帮我解决这个问题吗？谢谢。
