the Rosh (Rabbi Asher Ben Yehiel, 1250-1327) and others maintained that one does not recite “She’he’heyanu” before performing Bedikat Hames, because this Misva is incorporated into the broader framework of the celebration of Pesah. According to this view, the Beracha of “She’he’heyanu” recited on the night of Yom Tov covers all the Misvot associated with the holiday. Thus, for example, a person does not recite “She’he’heyanu” upon completing the construction of his Sukka before Sukkot, since the “She’he’heyanu” recitation on the first night of Sukkot covers all the Misvot relevant to the festival, including the building of the Sukka. Similarly, then, one should not recite “She’he’heyanu” when searching the home for Hames, as this Misva is part of the general framework of the Pesah celebration.
