Take a look at the paper "Tools for Printing Indexes" by Bentley and
Kernighan in _Electronic Publishing_, Vol. 1, No. 1, April 1988,
pp. 3-17.  As the last line in the summary says "An appendix contains
a complete listing of the programs, which total about 200 lines [of nawk]."

More important, the appendix says that you can get the programs in
machine-readable form by sending the mail message "send indexing.tools"
to either netlib@research.att.com or netlib@anl-mcs.arpa (I see from
the DNS that the latter is now peace.mcs.anl.gov.)

I used the programs for my book and they work great.  But, the hardest
part is figuring out the words you want to index, and inserting the
troff commands to create the raw data for these programs.
