Abstract
Disclosed is a computer program stored in a computer readable storage medium according to an exemplary embodiment of the present disclosure. The computer program executes operations for enhancing search performance of data when the computer program is executed by one or more processors and the operations may include: setting a traverse time stamp of an index search for searching a target index key; searching the index tree along a link connected from a root node of the index tree to a leaf node; writing in a time stamp table at least one index time stamp of the root node and the leaf node passed in the index search; determining whether a path of the index search needs to be changed; and determining a start node of re-search at least partially based on the time stamp table.
