How can I have 2 or more distinct indexes in LaTeX?

I would like to have 3 index sections: one for the biological species, second for chemicals and the third for other contents).

The question

1. is should i have a single index with together two as appendix?
2. is it possible to have 3 index categories.

In any case, i would like to have an example file with usage.

A good start for you would be to look at the imakeidx package manual. –  Thorsten Donig Dec 18 '11 at 16:22

The following post has an answer that describes how to use the multind package

How can I have 2 or more distinct indexes in LaTeX?

As @egreg mentions in one of his comments, there is also the imakeidx package- below is a MWE taken (pretty much) from the documentation (page 6, just before Section 4)

\documentclass{article}
\usepackage{imakeidx}

\makeindex[title=Concept index]
\makeindex[name=persons,title=Index of names,columns=3]

\begin{document}

Here is a list of things and people
\begin{itemize}
\item \LaTeX \index{latex}
\item Beccari \index[persons]{beccari}
\item Gregorio \index[persons]{gregorio}
\end{itemize}

And this is the end of the story.

\printindex

\indexprologue{\small In this index you’ll find only
famous people’s names}
\printindex[persons]

\end{document}
