Abstract
A key is divided into a plurality of key fields. Then, a corresponding first bit is determined from a bitmap top (BT) based on a first key field in a front part. Finally, a target bitmap bottom (BB) is determined, based on a second key field in a rear part, from a plurality of BBs corresponding to the first bit. In this way, for keys having a same first key field, a plurality of same BBs can be located through the BT.
