我想写一份我硕士论文使用的参考书目。我根据参考文献的类型对它们进行了分组，但我的问题是参考文献没有排序。
我的 .bib 文件是这样的

我想根据参考文献的类型（书籍、软件包、硕士论文等）对参考文献进行分组，所以我写了这个 .tex 文件
\documentclass[inscr,ack,preface]{dithesis}
\usepackage[backend=bibtex]{biblatex}
\addbibresource{references.bib} %my .bib file is called references.bib
\begin{document}
%My document
% manually include the bibliography
\bibliographystyle{plain}
%\bibliography{references}
% include it also in ToC (do sth on your own)
\addcontentsline{toc}{chapter}{Βιβλιογραφία} %Βιβλιογραφία is the name of the chapter in Greek
\chapter*{\bibname}
\addcontentsline{toc}{chapter}{\bibname}
\begingroup
\let\clearpage\relax % Disable page breaks within this group
\printbibliography[type=misc, title={Μελέτες}] %for the studies
\printbibliography[type=online, title={Σύνολο δεδομένων}] %for the data source
\printbibliography[type=book, title={Βιβλία}] %for the books
\printbibliography[type=manual, title={Πακέτα στην R}] %for the packages in R programming languages
\printbibliography[type=thesis, title={Διπλωματικές Εργασίες}] %for master theses
\endgroup
%\nocite{*}
\end{document}
输出如下图所示第一张图片 第二张图片。正如您在这些图片中看到的，参考文献已分组但未排序。您认为我应该怎么做才能使它们保持分组和排序。我搜索了很多，但还没有找到有用的东西。您能给我提供 LaTeX 代码吗？
答案1
用以下方式替换你的\usepackage[backend=bibtex]{biblatex}线路\usepackage[backend=bibtex,defernumbers=true]{biblatex}
