I use imakeidx which is great except for the fact that it is not clear enough what numbers are page numbers and what the rest.

Here is the example:

enter image description here

It is hard to distinguish that 88 is page number and 1 Kön 8, 12 index entry.

Is there a way to make all index entries bold by default and add colon after index entry? Like this:

1 Kön 8, 12: 88

I presume that this can be done with renewing \index command but I am not sure how.

Here is my MWE:

\usepackage[nonewpage]{imakeidx}% MULTIPLE INDICES
\makeindex[name=band1-bibelstellen,title=Bibelstellen, intoc, options= -s untitled.ist]
\makeindex[name=band1-themen,title=Themen, intoc, options= -s untitled.ist]
\makeindex[name=band1-personen,title=Personen, intoc, options= -s untitled.ist]
\blindtext\index[band1-bibelstellen]{1 Kön 8,12}
\blindtext\index[band1-themen]{Epiph.!haer.!8, 16}
\addcontentsline{toc}{chapter}{Alex. Al.!ep. encycl.!1, 12}

  • This isn't related to imakeidx itself -- you would get the same 'error' with makeidx -- it's caused by the way of information is given to \index or using a different .ist file for the index

  • I don't get any error. The question is about customising index entries and I useimakeidx so that is why I mentioned it.

  • @eklisiarh: That's why I wrote 'error' ;-)

Ok after 12 hours of trying, based on the solution suggested by Christian Hupfer (thank you!) and this page: https://linux.die.net/man/1/makeindex here is the solution:

Add this code to your .ist file

item_0 "\n\\bfseries\\item "
item_1 "\n\\bfseries\\item "
item_2 "\n\\bfseries\\item "
delim_0 ":\\quad\\normalfont "
delim_1 ":\\quad\\normalfont "
delim_2 ":\\quad\\normalfont "

and -c to the options parameter.

Also you have to remove nonewpage parameter because this doesnt work with .ist.

The solution for that is to add:


in front of:


That creates error \clearpage undefined so if you want you can put \batchmode in front of \printindex or you can use this solution: nonewpage option in imakeidx prevents me from using an .ist file

  • nonewpage is nonsensical with the scrbook class.
