**Context**
Touching to the end of my project and attacking `biblatex` (wild beast).
[This answer](https://topanswers.xyz/tex?q=1491) enables to format the (undervalued) `abstract` field of the `.bib` in a pretty `tcolorbox` and include the abstract directly in text.

[This answer](https://tex.stackexchange.com/questions/249336/bibliography-style-with-abstract-and-numbered-references) shows how to incorporate the abstract field in the bibiliography (I was surprised that `abstract= true` was not possible in the field settings).
[This answer](https://tex.stackexchange.com/questions/199336/biblatex-reference-both-by-chapter-and-at-the-end-of-the-book) shows how to input a bibliography at the end of each chapter and also at the end of the book.

**Question(s)**
Based on MWE below:
**1. Automatically put a bibliography including `abstract` field at the end of chapter.**
Manually inputing
`printbibliography[segment=\therefsegment,heading=subbibliography]` at the end of each of my chapXX.tex seems improvable.
**2. Input a full bibliography at the end of the document, WITHOUT abstracts**
Two problems in one, the bibliographies by type (article/book/report) don't show up, and I'd like them to appear without the `abstract` field.
**MWE**

You can redefine `\renewbibmacro*{finentry}{\finentry}` before your final bibliography to remove the abstract from the end of the bib entry:
```
\documentclass{book}
\usepackage[%
refsegment=chapter,% Pour avoir une bib per chap
bibencoding=inputenc,
hyperref=auto,
style=authoryear,
giveninits=true,
citestyle=alphabetic,
sorting=nyt,
sortcites=true,
doi=false,
isbn=false,
url=false,
eprint=false,
autopunct=true,
maxnames=10,%
maxalphanames=3,%
hyperref=true,
abbreviate=false,
backref=true,
backend=biber%
]{biblatex}
\usepackage{hyperref}
\addbibresource{biblatex-examples.bib}
\renewbibmacro*{finentry}{\printfield{abstract}\finentry}
\usepackage{xpatch}
\xpretocmd{\chapter}{%
\ifnum\value{chapter}>0
\printbibliography[segment=\therefsegment,heading=subbibliography]
\fi%
}{}{}
\begin{document}
\chapter{First chapter}
\cite{padhye}.
\chapter{Second chapter}
\cite{kastenholz}, \cite{itzhaki}.
\chapter*{Bibliographie}
\addcontentsline{toc}{chapter}{Bibliographie}
\renewbibmacro*{finentry}{\finentry}
\printbibliography[heading=none]
\end{document}
```
