For a moment there, I misunderstood, and thought that you were saying that
searching for "formula" was the answer. Here, I get 23 hits with Online
Content enabled, and 9 with it turned off... and--as you discovered--NONE of
them have anything whatsoever to do with table math, the = field, etc..
If I could actually find any help on it, I could then reverse engineer some
working search terms... but, as far as I can tell, there does not seem to be
anything about this in the Help file.
One thing I miss from OS/2 is that you could do an actual search of the help
file--you were not limited to the terms that are indexed. This gave
tremendous capabilities to quickly find what you're looking for. The fact
that we can't search the help files directly in Windows applications means
we're at the mercy of some indexer's limited imagination.
