In the directory where you installed docindexer, there's a file named
conf.py, a piece of Python code that describes the docindexer parser
configuration.  Its syntax should be self-explanatory; you can add
entries there for whatever source files you'd like to index.

Having said that, I don't think docindexer is the right tool for
indexing program source files.  Lucene text analyzers are biased
towards indexing plain text, so they typically ignore one-letter
words, like "a" and "i", words like "the", "in", "on", "some", etc. --
which could well be valid identifiers in a program.  It really isn't
the tool for this job.

For indexing source code, ID-utils is what you want; it doesn't
currently have an ELisp parser, but if you are willing to index *.el
files as plain text, you can tweak the id-util.map file to tell mkid
to treat *.el files as text (a plain text _is_ included in ID-utils).
If that's not good enough, writing an ELisp parser should be hard.
