Is there an easy way to hide comma (,) from the end of the indexed words?

Question

I use

\usepackage{makeidx}
\makeindex

and then I index a word as \index{word}. After \printindex in the Index it is appear as

word, 1

and I want it to appear as

word 1

But I don't know how to make it.

Answer 1

Prepare a file <main>.mst, where <main> stands for the name of your main TeX file, containing

delim_0 " "
delim_1 " "
delim_2 " "

and save it in the same folder containing your main file. For instance, if you have thesis.tex, you should name the new file as thesis.mst.

Then running makeindex will load the file and commas will be removed.
