That is an example of a nested OR that works fine. 

A00245 SEARCH ALL FROM YEAGER NOT (ALL TO YEAGER) NOT (ALL CC YEAGER)
* SEARCH 76 334 354 369 373 374 375 376 393 396
A00245 OK SEARCH completed

The above is "from yeager AND NOT (to yeager OR cc yeager)"

The simple application of De Morgan's laws is all that is required to do
complete logical searches with NOT, OR and AND.
