Well, I certainly did use the installer, and I do have that file. Are
you sure you don't have it?
In any case, you can find it in the docindexer source distribution.

But I just did change that. Here's the exact recipe:
. Find config.py in the docindexer installation directory and edit it
to add a line for *.el files.
. Find a file named library.zip in the docindexer installation
directory. This is the class library used by docindexer.
. Replace the file docindexer/config.pyc in library.zip with the
edited docindexer/config.py. Note: the .pyc extension means that
the file was compiled by Python; the corresponding .py file is not
compiled, but it will be used anyway -- this is similar to what
Emacs does with *.el and *.elc files.
. Run "docindexer --config" and make sure you see the *.el line in
the output.
After performing the above procedure, I have just indexed the entire
Emacs lisp/ directory. It took 3 minutes (yes, the indexer is not
very fast, which is why it's scheduled to run at night when I'm away;
mkid does the same job 3 times faster).
Morale: Never underestimate the power of Free Software! When you have
sources, _you_ are in control, not the software developer. This is
what Free Software is all about.

Is it really handy? Lisp identifiers include punctuation characters
such as `-', `>', `:', etc. I'd guess that plain text indexing will
not index these identifiers as you'd want to.

I'd rather extend id-utils.el, and eventually add that to Emacs.
