There is rampant misunderstanding of some parts of this article; allow me to help :)
The "no-search" chess engine uses search (Stockfish) in in two ways:
1. To score positions in the training data. This is only training data, no search is performed when actually playing.
2. To play moves when the position has many options with a 99% win rate. This is to prevent pathological behavior in already won positions, and is not "meaningful" in the objective of grandmaster-level play.

Thus, "without search" is a valid description.
