The Rabbi in our Shul (he learned in Brisk) has a tradition that the night before Pesach, after Maariv and before everyone goes home and does the search, repeats the Halachot Bedikat Chametz and that takes about fifteen minutes. Is that correct? Do we not have to begin the search a.s.a.p.?

Horav Dovid Pam’s Shlit’a opinion is that it is correct since the time elapsed is short and revising what one has to do is most important.
