http://www.ada-auth.org/cgi-bin/cvsweb.cgi/ai05s/ai05-0177-1.txt?rev=1.5
(found via the Schonberg presentation notes).

Question about the Ada-auth.org search programs:

search-acaa.cgi:

The results for "expression function" differ from those
for "expression functions" and AI 177 doesn't turn up
using the former parameter.


search-ai05s.cgi

Results differ, but AI 177 turns up (not a surprise, I should
think).

Q: Is it worth while adding singular or plural forms automatically?
Will doing so do any serious harm?  Copying the ubiquituous "+"
operator convention (indicating "as written, please!") can turn
this off, again.

(Word lists and algorithms are available in the free Unix
spelling libraries.)
