Yes, however if you search for "Maneuvering Characteristics"
near "Augmentation System" with the date limit you
do get a result.
The actual search is (with date before 1 Nov 2018),
["Maneuver Characteristics" AROUND(10) "Augmentation System"]
This throws up a PDF
FCOM for 737-800 from Newgen/Sabaidee. The reason it doesn't match your search is that the expansion of MCAS is split over two lines. The only match in the document is a glossary entry:
It is possible that the glossary is (or is intended to be) common to -800 and MAX documents, it is also possible that there are no other hits because other 737 FCOMs online predate the change and there are no MAX FCOMs online. It doesn't really tell us much except that there was a clear intent to document MCAS in some way - whether it actually was documented or how well we don't know. I'd be interested in what was in the AMM, if anything.
