Wie erhält man die Indexmarkierung?

Question

Ich möchte diese Lesezeichen haben.

aber ich bekomme nur dies:

Gibt es eine Möglichkeit, diesen Index mit den Markierungen im Bild zu erhalten?

\documentclass{book}
\usepackage[utf8]{inputenc}
\usepackage{imakeidx}
\usepackage[usenames,dvipsnames,svgnames,table]{xcolor}
\usepackage[pdftex, bookmarksnumbered,  pagebackref, colorlinks=true, citecolor=Blue, linkcolor=DarkBlue!30!Black, urlcolor=Black,bookmarksopen]{hyperref}
\makeindex[columns=3, title=Alphabetical Index, intoc]

\begin{document}

\tableofcontents
\chapter*{Dedicatory}
   to all my family
\chapter*{Abstract}
   hello world
\chapter{chapter}
\section{Introduction}
In this example several keywords\index{keywords} will be 
used which are important and deserve to appear in the 
Index\index{Index}.
 \subsection{subsection}
Terms like generate\index{generate} and some\index{others} 
will also show up. Terms in the index can also be 
nested \index{Index!nested}

\clearpage

\section{Second section}
This second section\index{section} may include some special 
word, and expand the ones already used\index{keywords!used}.

\printindex
\end{document}
