...atter ) or 2 * k2* nq / (1+L) as the length of the query is not needed in any way to build the Eset (Please do correct me if I am wrong about any assumptions Ive made so far ) . So,in order to use BM25 for weighing terms for Eset,we only need to modify the "multiplier" data member of the Expandstats class and then the final weight can be returned by ExpanWeight::get_weight( ) as (multiplier*tw) where tw will obviously be same for both the weighing schemes.Thus,depending on the weighing scheme and the parameters specified by the user in Enquire.get_eset( ) , multiplier can be calculated differ...
