我想打印一份包含具有特定关键字的所有条目（可能还有一些附加条目）的参考书目。
我知道当我使用以下方法打印参考书目时，我可以通过关键字进行过滤
\printbibliography[keyword=<keyword>]
但这只会打印我引用的条目。当然，我可以使用
\nocite{*}
将所有条目添加到参考书目中，然后只打印我想要的条目。
.bbl然而，由于我的数据库非常庞大，这会使我的文件变得非常大。
另一种可能性是使用 Biber 或其他工具准备一个.bib仅包含带有关键字的条目的文档特定文件。但是，如果将带有关键字的其他条目添加到我的主要数据库文件中，则需要重新创建该文件。
这是一个可以使用的 MWE，带有注释以表明我希望它工作的方式；）以及它（几乎）工作方式的缺点。
排除明确引用的条目的问题对我来说不是什么大问题。我真正想解决的问题是将整个数据库内容添加到.bbl。

更新：现在可以使用 biber 2.14/biblatex 3.14 来实现，它们都位于 github 上的各自开发文件夹中[1][2]：
\documentclass{article}
\usepackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@book{new-stuff,
author = {Watt, Brian},
title = {Happy Times with Penguins},
publisher = {Harvard University Press},
address = {Cambridge, MA},
year = 1995,
pagination = {section},
keywords = {happy}}
@book{den-coll,
author = {Till, Jr., Dennis E.},
booktitle = {Penguin Land and Further North: Human Influence},
title = {Penguin Land and Further North: Human Influence},
publisher = {Oxford University Press},
year = 2008,
address = {Oxford and New York},
keywords = {penguin, human}}
@book{old-stuff,
author = {Harvey, Jr., Dennis E.},
booktitle = {Penguin Land and Further North: Human Influence},
title = {Penguin Land and Further North: Human Influence},
publisher = {Someone \& Daughters},
year = 1567,
address = {Oxford},
bookpagination = {paragraph},
keywords = {penguin}}
\end{filecontents*}
\usepackage[defernumbers=true]{biblatex}
\addbibresource{\jobname.bib}
\DeclareSourcemap{
\maps[datatype=bibtex]{
\map{
\step[nocited, final]
\step[fieldsource=keywords, notmatch=happy, final]
\step[entrynull]
}
}
}
\begin{document}
\cite{old-stuff}
\nocite{*}
\printbibliography
\end{document}
这会在解析数据源时删除已删除\nocite或没有关键字的条目。

这是一个老问题，似乎没有真正令人满意的答案。但这里有一个解决方案，涉及一个perl脚本，只是为了好玩。
记得用 来运行它pdflatex --enable-write18。
