（第二篇帖子）以下是更新后的代码，它显示，在注释索引包时，我在索引中为术语 alldifferent 获得了两个单独的条目（一个用于定义，一个用于出现）。但是，如果我放入索引包，我只会获得 alldifferent 的一个条目（应该如此），但我再也得不到解释性文本了。

（初始帖子）当将 makeidx 与 book 类一起使用时，有没有办法在索引页中添加一段解释性小文本（请注意，由于我使用的是 .ist 样式文件，因此我更喜欢使用 makeidx 而不是使用某些帖子中建议的 splitidx 或 imakeidx 包；因为我还使用 book 类，所以我不想按照其他帖子中的建议切换到 memoir 类）。
由于我不完全确定应该在哪里添加您建议的代码，因此我添加了一个可以编译的文档小示例：
\documentclass[]{book}
\usepackage{makeidx}
\usepackage{index}
\usepackage[plainpages=false,pdfpagelabels,colorlinks,linkcolor=cyan,
citecolor=cyan,urlcolor=cyan,bookmarks,
hyperindex=false,pagebackref=true]{hyperref}

titi \index{titi|indexuse}
\cleardoublepage
\markboth{INDEX}{INDEX}
\phantomsection
\addcontentsline{toc}{chapter}{Index}
% Page numbers in bold face (as in \textbf{160}) point to a definition
% of a constraint, keyword, restriction or system. Page numbers in
% bold-italic face (as in \textbf{\textit{160}}) notify an abbreviation
% of a constraint name. Finally, page numbers in serif face (as in 160)
% indicate an occurrence of constraint name, keyword, system or author name.
\printindex
\end{document}
最后，catalog.ist 文件包含以下几行：
preamble "\\begin{theindex} {\\small\\onecolumn\\newcounter{idxl}\n"
postamble "\n\n} \\end{theindex} \n"
group_skip "\n\n \\vspace*{12mm}\n"
heading_prefix "{
\\bfseries\\Large\\hfill "
heading_suffix "\\hfill}\\nopagebreak\\vspace*{4mm}\\stepcounter{idxl}\n"
symhead_positive "1..."
headings_flag 1
答案1
您可以使用idxlayout，这样也可以避免发出\onecolumn。这是修复后的.ist文件：
preamble "\\begin{theindex} \\small\\newcounter{idxl}\n"
postamble "\n\n \\end{theindex} \n"
group_skip "\n\n \\vspace*{12mm}\n"
heading_prefix "{\\bfseries\\Large\\hfill "
heading_suffix "\\hfill}\\nopagebreak\\vspace*{4mm}\\stepcounter{idxl}\n"
symhead_positive "1..."
headings_flag 1
这是示例，其中我填充了索引来显示标题和目录中的条目如何符合需要。

答案2
您不需要任何特殊的包。makeindex只需将\begin{theindex}...写入文件\end{theindex}中.ind，这样您只需定义该环境即可执行任何您想要的操作这是 article.cls 中的定义，其中添加了一段文本
\renewenvironment{theindex}
{\if@twocolumn
\@restonecolfalse
\else
\@restonecoltrue
\fi
\twocolumn[\section*{\indexname}
this is a paragraph spanning a 2-column index
a second paragraph
]%
\@mkboth{\MakeUppercase\indexname}%
{\MakeUppercase\indexname}%
this is a paragraph in the first column of the index
\thispagestyle{plain}\parindent\z@
\parskip\z@ \@plus .3\p@\relax
\columnseprule \z@
\columnsep 35\p@
\let\item\@idxitem}
{\if@restonecol\onecolumn\else\clearpage\fi}
在您稍后添加的示例上下文中看到这一点，请注意我group and从 ist 文件中删除了错误的 \clearpage`。
