The use of primary effects in goal-directed search is an effective approach to reducing the search time. The underlying idea is to identify important effects of every operator and to apply operators only for achieving their important effects. For example, the main effect of lighting a fireplace is to heat the house; we call it a primary effect. If we have lamps in the house, illumination is not an important result of using the fireplace. We view it as a side effect,which means that we would not light the fireplace just for illumination.
